Hello again.  I've recently rescued this old scope from my local club, and wanted to confirm its identity with the renown classic telescope community.  I BELIEVE what I have is one of these:

That is, the 12X40 guidescope of a #20TE.  Unfortunately, the scope badge is missing (If there ever was one), and the scope was painted in a horrible baby blue when I found it.  I have since sanded the blue off revealing the original white, and I intend on touching it up with a light coat of gloss white.  It will then find new life as an auxiliary finder on my 76 mm Royal.  What do you think?

 

Pictures after a THOROUGH cleaning and sanding of the blue paint.:

Great find.  I had the Unitron 10x40 mounted piggyback on my Tasco 7TE-5.  Looked very cool for those days :)

Royal put those 40mm guide scopes on several models:  Sears 6345, Lafayette Galactic, Tasco 20TE, etc.

 

Mine had a very good lens.

I had it out two nights ago for the full(ish) moon.  Almost NO discoloration, I was very impressed.  I think it'll be a fine scope.

That looks more like the 50/500mm guide scope.  I have both the 40 and 50mm varieties.  Check the objective size.  Also, the objective cell is more like the 50mm.  I don't believe any of the finder scopes came with a badge.  At least none I've ever seen.

 

Here's the 40mm on a Lafayette Galactic and the 50mm by itself.  Astro Optical used the 50mm guide scope on their R-101 and R-102 scopes.
