This Gestetner Cyclostyle duplicating machine was invented and manufactured by David Gestetner. He claimed in 1922, once he had released several models, that if a Gestetner Durotype stencil was used together with his Cyclostyle machine, then 10,000 copies could be made from the one Durotype stencil, an amazing claim for office technology of that era. David Gestetner (1854-1939), was born in Csoma, Hungary. He has been called the “founder of the worldwide office copying and duplicator industry.). He moved to London and in 1879 filed his first copying patent. In 1881 he patented the Cyclostyle stylus (or pen), which was used in conjunction with his Cyclograph device for copying text and images, He established the Gestetner Cyclograph Company in England at this time (1881) to protect his inventions and to produce his products; stencils, stylos (stylus or pen) and ink rollers. HIs inventions included nail-clipper and the ball-point pen (although the latter is more commonly associated with Laszlo Biro). Gestetner’s patented Cyclograph duplicator was used with his Cyclostyle Stylus or pen to write or draw on special thin wax-coated stencil paper (originally used for kite making paper) in the following way; 1. The Cyclostyle stencil was placed on a lower, framed metal plate of the Cyclograph 2. An upper frame was clipped over the top 3. The Cyclostyle pen, with its tip being a small metal-spiked or toothed wheel, was used to write or draw on the stencil, punched small holes into the paper and removed the wax coating in those places 4. The upper frame and stencil was then removed and a piece of blank paper was placed onto the metal plate in the lower frame and the upper frame with stencil was replaced 5. A roller was given an even distribution of Cyclostyle ink and rolled by hand over the stencil in the frame. This forced the ink through the holes in the stencil to and made a copy of the stencil on the paper 6. The upper frame was raised, the printed paper removed and another blank sheet was put into place. The whole process was repeated until enough copies were made. Gestetner’s invention developed further in 1894, with a stencil that could be placed on a screen on a revolving drum. The drum was manually rotated, the stencil then wrapped around another drum and was fed between cloth-covered rollers on which ink was evenly spread. Each revolution of the drum forced ink through the holes in the stencil and transferred the ink onto paper that had been fed between rollers and pressed against the drum. The process was repeated for each page. The paper was still fed and removed manually in this earlier invention but became more automatic in later models. In 1902 Gestetner duplicator model 6 was put onto the market. This model included the improvement of an automatic paper feed that synchronised with the rotation of the stencil. The Gestetner machine was the first office printing machine. It was easily installed and it made exact copies of the sane document quickly, effectively and inexpensively. This changed the way offices operated, making information easily available to many more users. The machines were commonly used in small businesses, schools, churches, clubs and other organisations for the wide distribution of a wide variety of information in the form of worksheets, newsletters and more. In 1906 the Gestetner Works were opened in Tottenham Hale, North London, and thousands of people were employed there up until the 1970’s. Due to the fast growing success of the Gestetner Duplicator machines many international branches for sales and service centres were established. David Gestetner was succeeded by his son Sigmund, followed by his grandson’s David and Jonathan. Further advancement was made by using a manual typewriter with specifically designed stencils. The end product was a printed, typewritten copy similar to the print from newspapers and booklets. In the next few years there were further developments of this revolutionary invention. The Gestetner Cyclostyle duplicator in our Collection is dated c.1922 - 1929 and it uses Gestetner Durotype stencils The 1922 British Industries Fair’s catalogue contained advertising for the Gestetner Rotary Cyclostyle “The World’s Premier Duplicator”, demonstrated at Stand K 86.” A Notice at the foot of the advertisement’s page boasts "Important - D Gestetner's latest invention, the "Durotype" Stencil, enables you to obtain 10,000 copies from one original if desired. It contains no wax of any description, is indestructible, can be stored indefinitely and printed from as required” In 1929 the look of the Gestetner machines changed; American designer Raymond Loewy was invited by Gestetner to improve the look of his duplicators, resulting in a very streamlined appearance. Eventually, around 1960’s, offices replaced their Gestetner with small photocopying machines and printers. Gestetner took over ownership of other office machine companies over time, including Nashua, Rex Rotary, Hanimex and Savin and eventually all came under the holding company name of NRG (Nashuatech, Rex Rotary and Gestetner). In 1996 Ricoh acquired the Gestetner Company, and it was renamed the NRG Group.

This item relates to methods of reproducing photos on all forms of material in an era of physical offset printing.The offset method is being replaced by digital transfer direct to the final product,(paper or other porous and non porous surfaces). Newspapers and other "paper" information publications are still producing "hard copies" but these are slowly being phased out. This item was used Circa 1920s in the peek period of paper based media. From the 1940s radio and then television stepped into the mass media revolution.This book was produced when all printing, Government and private enterprise, was using the "off set" method. This method was used to a great degree in all schools within the Kiewa Valley. It was in an era before "photo-copying machines" were available. This was a period when printing inks for larger printing machines had to be purchased from specialised outlets and printing presses required to be washed after each "run" of printing before the next plate(aluminium) could be fastened onto the "off sett" machinery. Heat infusion now used in large machines and domestic printers has superseded this task.

This banknote plate was created for the Sydney branch of the Bank of Australasia in February 1900, before the Federation of Australia. After printing the banknotes from this plate the printer would have overprinted the banknotes with a unique serial number and the denomination of the banknote in capital letters using a contrasting ink. The Bank of Australasia was incorporated by Royal Charter of England in March 1834. It first came to Australia on 14th December 1835, opening in Sydney. In that year, the Acting Superintendent of the Bank of Australasia in Sydney was David Charters McArthur. He went on to become the Superintendent from 1867-to 1876. The Melbourne branch of the Bank of Australasia opened on 28th August 1838. In 1951 the Bank of Australasia amalgamated with the Union Bank to form the Australia and New Zealand Bank, now known as the ANZ. Then in 1970 the ANZ merged with both the ES&A and the London Bank of Australia to form the ANZ Banking Group Limited. The ANZ Banking Group Ltd kindly donated a variety of historic items from the Bank of Australasia. BANK of AUSTRALASIA, WARRNAMBOOL – The Bank of Australasia was the first bank in Warrnambool. It was established in 1854 and operated from leased buildings on Merri Street and then Timor Street. The bank opened its own building on May 21, 1860, on the northeast corner of Timor and Kepler Streets. Mr A Butt was the Manager of the Warrnambool Branch in 1895. This significant item of early Australian social history gives a snapshot into the founding and early development of the banking system in Australia. The plate has historical significance as it belonged to the Bank of Australasia which was established in 1834 by Royal Charter and opened in Sydney, Australia, in Sydney in 1835. The plate is significant for its association with the Bank of Australasia, which had a branch in Warrnambool. Warrnambool's branch was the first bank in Warrnambool, established in 1854. The bank continued to operate until its merger in 1951 when it became the ANZ Bank, which is still in operation today. The Bank was an integral part of the establishment and growth of commerce in Colonial Warrnambool and throughout Australia.Printer's plate for a five-pound note, attached to a block comprising several layers of different varieties of wood.

The Mark II Pilot Balloon Slide Rule was made of wood laminated with heavy white plastic with a length of 24.5-in. and width of 2.5 inches. Mark II rules were manufactured in Australia by W & G (Melbourne). The W & G rule differs only slightly from the English A. G. Thornton LTD rule. The W & G rule uses serif fonts and has some fiducial marks that the English rule lacks. Exact dates of production are not known but the MK II is known to have started production by 1927. The printed scales are engraved in the plastic faces. The slide rule has 4 captive cursors (glass windows and brass guides) that ride in slots on the top and bottom edges. Each can be moved independently of one another. The cursors are missing from this item. Brass knobs at both ends of the slide facilitate its movement. The case is fabric covered wood with felt lining. No known history for this item as located in a property after purchase. The Pilot Balloon slide rule is used to convert the observed azimuth and elevation readings into wind velocity and direction records. The use of slide rules was abandoned with the wide spread adoption of computers and programs to do the calculations, as well as the decline in the use of optical pilot balloon theodolites.Made in Australia by White & Gillespie (Melb) Pty Ltd. Established in 1910, the firm was involved mainly in printing plate manufacture, but during the Second World War it manufactured a variety of navigational aids and range finding devices for the military.
