Came with my TV telescope, but I needed the all brass, weight compensator version (which I just got). In like new condition; I think I might be able to see one single setscrew mark. This item has a setscrew. I actually like that feature better than my new compression adapter. Eyepieces are MUCH easier to get in and out. Anacortes wants $45 for one, this one can be yours for $25 + $3.95 shipping.
