How many of the aluminum GGTS's you made?
Aluminum only not the nickel.....although one of those are next on my list to look for....
And nickel does better than alum
Well, I don't know bout aluminum telescopes as I've never seen one, but if you use the wiki serial list as a reference the aluminum GGTS's go up into the #800's before the nickel ones appear. Both my rev 2's are alumunium with brass tele's, buttons and draw caps only. Bottom caps are aluminum.
