1. I have an old .965" Towa Star Diagonal that is missing it's Prism.
These were quite often found in Tasco and Sears Telescopes.
Perhaps you have a spare from a broken diagonal?
I believe it's the same size Prism as used in the older Bakelite bodies.
Measurements are given on the photos

2. I also need a Prism and Cap for an old style .965"Porro I'm repairing.
An extra retaining screw would be a bonus.

Will pay a reasonable sum for either one.

I will consider complete replacements, but I really enjoy repairing this old stuff as opposed to throwing them out.
