From this post about an Ebay acquisition:
"Re the finder knob, it works but not from the normal clock face 12 to 3 position. Instead it works from the 3 to 6 position. So would this be something for repair by Questar or Company 7?"
Don't send it in. Get the small Bristol L-wrench (Ebay or Questar) and just loosen the set screw opposite the lever, adjust, and tighten. As easy as it gets. You'll want to visit this thread for most of the things mentioned here.
If you're ordering from Questar (call, don't email), consider if you want new eyepiece eye cups if any are damaged or worn.
They can also send you a new replacement warning label so you can remove the damaged one, and replace if there is a fading shadow.
I'll bet that Mother's wheels polish or equivalent will impress you with how it can restore those purple surfaces (finish with plain car wax).
You'll need to deal with the finder mirror screws. I did a post here about it, and also a 20-minute Youtube video on Questarzone.com. If you're not perfectly happy with the plating condition on the mirror, you may as well spend $30 and get it recoated like new.
