I tried numerous times today to get in contact with anyone at US Optics today but was unable to. I also looked up the SN9 that u said this was and saw several pictures that showed the way it was mounted to several platforms. After looking at those images and the ones from this link which details all of the Us Optics scopes from that era, it seems to resemble the SN3 more so. Not doubting your word at all, as I have never owned a USO product before this one. I wish they would have answered so I would have definitive info. I am more than willing to sell it to you as u know more so from first hand knowledge what it is. Here is the link I mentioned earlier.

I think you are right... that it is an SN-3 with an SN-9 style early front bell for adjusting parallax. It seems to have internally adjustable turrets. Sorry, I was looking at it on a phone last night. And didn't notice that the turrets were part of the erector. The Parallax is adjusted by turning the front bell, not on the erector as on the later scopes.
Should be a 22x. And actually WOULD be much more at home on a Barrett. The challenge with these in fielded conditions is you had to reach way forward to adjust your parallax. Most of the Barretts were fielded with fixed 10x. Which doesn't seem like a lot of power, but for an anti-material rifle worked fine and was really rugged.
I would give USO a couple of days. They won't be able to help much via phone. But if you e-mail them at:
[email protected] They will get back to you pretty quick. Put in the title "Info on older US Optics Scope" and include the serial number. They will be able to get the date info, etc. for you.
Here is an SN-9 on a .338 Lapua. It's as massive as it looks!!!
Fun picture of the SN-9 done by someone here on SH many, many years ago!! These are 35 - 40X scopes.
I'd still be interested in your SN-3 as I have a project rifle coming together that it will be perfect for...
But first I'd try and get info from USO. PM inbound!
And my apologies for mis-identifying it from the phone pictures... my bad!
Cheers,
