Recent scope purchases - Originals? How to clean & repair them?
I managed to win a small lot of scopes on auction, and they finally arrived today.

Lot was for 2x M73B1, 1x M82, and 1x M84. All but the M82 have what I think are the correct rings for an A4, and the 82 has what I hope is a USGI M1C mount.

Now, to be honest, I'm incredibly unfamiliar with optic maintenance and care. I've never really considered trying to get originals due to overall rarity and cost, but jumped at the chance to have such a wide range. I paid 3.3k in the end (hammer price was 2.8k, and I know a few folks here were also watching this auction).

Are all these originals? What should I do about the rust (especially on the M82)? I was thinking of a nylon brush with oil, but like I said, I don't know much and want to treat them right. I'd be happy if anyone can point me to a restoration company they thought would be up for handling these.

M73B1 #1: - serial # & model - overall scope - dirty glass -poor crosshair pic, but they look ok? - faint electropenciling

M73B1 #2: - scope - nicer electropenciling - broken crosshairs

M82: - serial & model #, so much rust - whole scope - other side - optics - Anyone got Garand #3,447,468?
I couldn't get a pic of it, but the mount has 2 lines of print. The Griffith & Howe name and then the patent # and date on the 2nd.

M84: - serial & model # - whole scope - worst spot of rust on this one - crosshairs look good - rubber is cracking a bit...

Oh, this...lens filter? was also included: I think it fits the Weaver scopes.

Overall, did I do alright with this? I know it wasn't the greatest purchase ever, but just hoping I was "in the ballpark" for value and didn't overspend too much. Also a bit sad that the one M73B1 has broken crosshairs, but that's the risk with these sorts of purchases. I'll probably keep all but one of the M73B1s, but I'll have to decide about repairing the one before selling. I've got a 1903A4 with a Lyman Alaskan B series scope on it currently, and I'm tempted to swap on that M84.

......Pretty sure I need an M1C now too.

The M82 and M73B1's you can unscrew the rear bell to clean the lens. But you will need a special tool to remove the retaining ring on the front of the scopes. I do not recommend trying it unless you know what you are doing. You could damage the lens or the ring and tube.

Just clean as best as possible.

I think you did very well. Had I gotten back sooner I may have ended up with them. (Memo to self. Leave a bid when going out during an auction.)

You have the hardest part of the M1C to find. You can get the rifle from the CMP.

I sent my M84 to Iron Sight Inc...4-6 month's been there 4 months...

I cleaned up some of the scopes over the last few days. Here's the M84 after scouring the rust spot with a copper pipe fitting (I didn't have any old pennies around) and some copper solvent.

And the scope overall after a gentle rubbing with cleaner and light oil:

I posted nicer of the two M73s for sale, since I'll probably keep the worn one for a project piece. The thing I did notice is that the lettering on the worn one wiped out unlike all the others. I wonder if the ink was removed ages ago and a previous owner just colorblocked the stamping? Would there be a "correct" fill for it I could get?

The M82 is proving to be a bit difficult. I would ideally get it off the mount to clean them both up separately, but I realized one set of the mounting screws are staked in. That's probably beyond me to remove, so I'm talking with Columbus Machine Works about them handling it. Not sure why just one set was staked and not the other...

I have used this company twice in the past ten years. For restoration of WW II USGI binoculars. Very good work.

I had an M84 completely disassembled and cleaned by Moutain Optics in California.Very quick turn around and cost $165.Scope came back with beautiful optics.

I actually sent the M82 and M73B1 to him! He's been super easy to get ahold of, and changed about $360 for both scopes. He was also able to get started on them about a week after I mailed them and can't wait to get them back. I'll post pics once I have the repaired scopes back.

I'm considering sending the M84 and my Lyman Alaskan B to him now as well...
