This item was produced for commercial shops and other traders in a period, 1800 to the 1950s. They were used because they were extremely cost effective, speedy, easy to learn and simple to use. It was also at a time before pocket calculators and electric cash tills were produced. The reckoners were a fast and accurate accounting book for a ever increasing bulk purchasing industry. These reckoners were at the start of a business principle "time is money" The reckoner was also looked upon as a way of reducing staff errors in the calculation field. This reckoner was highly valued to a rural industry in the Kiewa Valley because of the bulk produce being bought and sold here. Produce such as milk, tobacco, cattle, timber and fruits relied on weights and quantities calculation for cost pricing. Electrical machines were not of use in "the field or paddock" where important price negotiations took place. For a successful business to keep going accuracy was upper most to producers. It was still a time where honest transactions built reputations and tardiness ruined them. It was a time when a producer's word was his bond and a gentleman's handshake was as good as a contract. This attitude lasted a lot longer in rural regions than in the city. A producer's reputation was based on face to face negotiations and honesty.This hard cover book (blue in colour) contains 210 pages of black numbers and headings on light yellow pages (aged).

This calculator is like a modern calculator style keypad with a traditional pinwheel calculator. In operation it is similar to other Facit machines. The design from the 1930s was produced without interruption with only slight modifications until the early 1970s.This one hasn't a serial number or Model Number so date is unknown but probably the 1940s - 1950s when the SEC were constructing the Kiewa Hydro Electric Scheme.Used by the SEC Office Staff when the SECV were constructing the Kiewa Hydro Electric SchemeBox shape with grey steel top and sides on a black base. Three thin strips of stainless steel embossed with numbers on the top and clear panels beside them. Front has 3 red and 10 black knobs with arrows on the red and numbers on the black. Sides have stainless steel pedals and winders. The machine is very heavy. See on-line "mechanical calculators.wordpress.com"'Facit' on the front.calculator, facit

1946 One of the first Contex calculators, the Half-Keyboard Adder used Leibniz step cylinders to perform simple addition. The predominant use of this Contex would have been adding sterling currency. Starting from the right, the levers were used for half and quarter pence, the next row would be pence, followed by shilling up to 19, and pounds. On the far left there is a zeroing lever for the entire mechanism; Ref: Online: 'physicsmuseum.uq.edu.au'Used by the office staff at the SECV construction of the Kiewa Hydro Electric Scheme.Bakelite small typing machine consisting of numbers with a screen above.'Context' embossed centre front 'Lubrication' with instructions and with Patents on bottom 'Chartres Business Service' at back 'Numbers 1 - 5' at front on knobscontex, adding machine, office equipment

An adding machine is like a calculator enabling the user to do addition and subtraction and multiplication and division by repetition. Adding machines provided a printed receipt for each entry and calculators display information on a screen.Adding machines were used in the office and were replaced by calculators and comptometers.Used by a resident of the Kiewa Valley and possibly in the SECV office.Formerly UKV 242 or Contex UKV 253 - Electric (no cord).

The core memory of this calculator was a #D metal box. The pin must have been attached to a card reader or keyboard to enter the programme. According to Sharp’s serial numbering scheme, which encodes the month and year of manufacture of their electronic calculators at least through the mid-1970’s, this calculator was manufactured in September 1969. The technology used in the Memorizer 30/Memorizer 60 was very typical of that of the late 1960s, with small-scale integrated circuits containing a few gates or flip-flops, and a magnetic core memory array for storing the program steps that the user keyed in using the calculator attached to the device. (with thanks to Rick Bensene, Curator of the Old Calculator Museum, Beavercreek, Oregon, USA) ISharp Memorizer 60 (Model CSA-12). The Model CSA-12, called the "Memorizer 60", was an accessory that could be connected to a Sharp Compet 22 or Compet 32 electronic calculator to allow these machines to be "learn mode" programmed. Programs were "learned" from the keyboard of the calculator, and stored within a core memory array in the Memorizer 60. Programs of up to 60 steps could be stored. The Memorizer 60 could them "play back" the stored steps at high speed, to allow relatively complex math operations to be performed.
