The finder scope for my mystery scope is solid brass' The aperture is 40mm. Stamped in the tube is R 1336. The eyepiece has a slide to close the eyepiece instead of using a lens cap. It has a little pin that you can open & close with your thumb. I have seen similar slides on antique telescopes & binoculars of European manufacture. Again, I will appreciate any speculations on the manufacture & origin of my new "old telescope".
