Here is a military scope with some beautiful optics. The achromatic objective is 35mm diameter by 180mm focal length. The eyepiece has large lenses and is a 30mm focal length. It's probably a Plossl or
Erfle. The filter wheel has 4 stations: clear, red, yellow and variable polarizer. There is a nice cross hair reticle that can be illuminated externally with an LED or small bulb.
You can use as is, or "gut" it for some nice optics. The amici prism is the same as Edmunds #70826 (40.5mm x 53mm x 32m) - no longer available though. The filters, reticle, and amici prism all have about a 34mm clear aperture. The eyepiece could easily be machined down to 2". There is also a nice optical window with about a 45mm clear aperture.
I've got one complete scope for $75 OBO and one complete set of "guts"
for $75 OBO. Buyer pays actual shipping. Approximate weight is 15 pounds for the complete scope and 5 pounds for the "guts".
Don't be worried about amber (radioactive) optics. There are none here.
