UO 28mm Orthoscopic side view showing chrome barrel.
Long discontinued 28mm Orthoscopic eyepiece from perhaps late 1970's vintage. Might be even earlier as the eyepiece has a serial number U-2980. It is also described as a "flat top eyepiece", even though the cap in this picture clearly shows a semi volcano shape to it.

This is an 8 inch optical flat made of Zerodur ceramic glass. I use this flat for making refractor or cassegrain optics. The instrument next to it is a spherical digital micrometer which is accurate to within 50 millionths of an inch !! Al Paslow telescope collection
