Description

A fine No.1 binocular microscope by R&J Beck, 31 Cornhill, LONDON serial number 6632. (ON HOLD).

The microscope stands on a flat tripod base/foot, two supporting pillars, both terminating in trunnions supporting the microscope body, with large plano-concave swing-arm mirror (minor spotting) and sliding collar, substage condenser holder and screw X-Y/up-down adjustment. The stage has rack and pinion focusing to a large goniometer circuit stage allowing for full rotation of the specimen (demarcated from 0-180 degrees). Stage with X-Y controls, swept limb with single accessory holder,  fine focus mechanism acting on the rack and nosepiece.Wenham prism in pull out drawer, rack and pinion to the dual eyepieces (blued steel inter-connecting rod).

Although this microscope shows minor wear to the foot (see photo), the rest of the microscope has seen little use with 99% original golden lacquer intact. The circuit stage was a rare and expensive option in 1873.

Eyepiece, nosepiece and substage polarisers, hand forceps, selenite/specimen holder, wrench to tighten trunnions. Oddly NO double nosepiece objective changer. 

The flame mahogany case measures 20 x 12 x 10 inches deep with slide out base for the microscope and a bench condenser ( in rear), mounted on an angle typical of Beck. Original lock and key.
