Title
R & J Beck Compound Microscope
Description
The R & J Beck's compound microscope is made from lacquered brass with a continental horseshoe base which is solid brass and has etched "R & J. Beck. Ltd London 26669" into the back of the base. On one of the sides of the base, "WILLIAMS BROWN & EARLE PHILADELPHIA" is etched into the foot. The substage double-sided mirror — which includes a concave side — is attached via a gimbal arm to a swinging tailpiece that is connected to the pillar. The square, mechanical stage is painted black and has two metal clips to secure a specimen. There are two holes on both corners of the stage in which accessories such as stage forceps can be attached. However, there are not any stage accessories with this microscope. There is also a substage iris diaphragm that can be adjusted via a lever on the outside. The coarse focusing functions via a rack and pinion mechanism which moves the body tube closer or further away from the fixed stage. The fine focusing mechanism is controlled by a thumbscrew located at the top of the pillar. The fitted case is original to the microscope and has compartments on the inside of the door that hold the objectives and ocular lenses. The case has a brass carry handle on top of the microscope and the case is secured with a lock; however, there is not a key with the microscope.
The microscope comes with the following accessories: 2 ocular lenses, 3 objective lenses with brass canisters: "40mm R & J Beck Ltd 2IN" "16 mm R & J Beck Lt. 2/3" "4mm R & J Beck. Ltd 1.6"
