Abstract
The horseshoe base and the pillar are cast as one piece. The curved limb is attached to the base by means of trunnions. Below the square stage are the Abbe condenser, iris diaphragm, and a mirror. The body-tube with a triple nosepiece moves by rackwork, and the fine focusing is by a micrometer screw. No case and accessories. Signed: Spencer Buffalo U.S.A. 206665.
