My #826 was converted to a DOB.
I used the mount for my CR150.
Whats left over is the aluminum tube rings from the #826.
The 826 was the predesessor to the starfinder series, early 80s.
The tube rings seem to be cast aluminum and the tube size was 9.25 for the OD. Ring come with knobs and heavy thick felt for tube contact. One of the rings has 3 1/4-20 drilled at tapped holes in various locations for camera piggy-backing.
Asking $30 (20 for the rings and 10 to box/ship/insure/delivery confirmation).
Money Order or personal check only.
Oh, yes, rings are in good condition, and have been stored for almost 30 years, rings are heavy duty.
