Equipment - Object, American Optical Company, Fits-u eyeglasses pince nez trial fitting setting, 1900s
To be fashionable, and possibly improve vision at the same time, the pince nez style of glasses became popular. The 'Fits-u' design has a mounting that allowed the bridge to stay solid, whilst the springs in the nose pads allowed for removal (unlike pince nez which had a springs in the bridge). Although complete, this box includes models with different distance dimensions and the height of the bridge, with these figures are etched onto the lenses. An order table is included in the box with the pupillary distance and height so the catalogue number and quality and quantity of each size can be ordered by the dispenser. The pupillary distance is used to design spectacle frames.Canvas box which includes display models of different dimensions of pince nez Handwritten on the back: James Korp Backhouse (?) 1904 Ophthalmic Optician & Optometristassistive devices, american optical company -

Photograph - RASvy Surveyors in the field, c1950s – 1960s
This is a set of 1photographs of surveyors in the field measuring distances using chains, taking observations using theodolites and operating electric distance measurement equipment. They were probably employed in establishing mapping and geodetic control operations or the surveyors may have been in training. The photos were most likely taken in the 1950s and 1960s. Photos .1P to .6P feature personnel setting up geodetic survey chaining equipment to measure distances. The surveyor in Photo .5P is LTCOL Howard Angus Johnson MBE who served from 1936 to 1954. The RA Svy surveyor in photos .7P to .12P were using a theodolite to take angular measurements. They were usually supported by an observer who recording their readings on a booking form. The surveyor in Photo .10P and .11P is LTCOL Jorge Gruszka, who served from 1955 to 1985. He was CO of the Army Survey Regiment from 1982 to 1985. The surveyor in photo .13P is cutting an identification blaze on a tree using a hammer and chisel. The tellurometer in Photos .14P to .16P was a MRA1 microwave Electronic Distance Measuring instrument (EDM) introduced in 1958. It and later models were man-portable systems that improved geodetic survey efficiencies for rapid network extension and densification replacing triangulation with EDM and theodolite traverse sometimes using Bilby Towers to extend line lengths. The surveyor with the slouch hat is Colonel James ‘Jim’ Leslie Stedman, who served from 1941 to 1978. He was Director of Military Survey from 1975 to 1978 and was appointed as Colonel Commandant (honorary appointment, Retd) of the Royal Australian Survey Corps from 1978 to 1983.
