Leitz Wetzlar W 10X 30mm Microscope Eyepiece - 2 Part w/ Male Threads - Vintage

Description

Leitz Wetzlar Germany W 10x eyepiece comes in two parts that pull easily apart. One half is the usual eyepiece and steel tube, while the other is anodized metal with additional glass that has a threaded male end, presumably for screwing into a scope body or headpiece.
Two available. One is 75.5mm from end to end, the other is 78.66mm from end to end. The threaded end on both is 30mm in diameter, and the steel tubes on both are 30mm.
These are vintage/antique eyepieces and show expected wear, but look to be in fairly nice condition for age.
