Poor quality, dark photos.
(I have a good computer, but I had to use a photo editor to see the details)
No front frame view where full serial number is or under the barrel.
My only surprise was that each had a reserve of only $500.
That interested me. I don't think they are collector quality, but they look functional and complete.
#5 (Item # 539177141 ) was pretty heavily buffed out, probably to hide some kind of mis-match.
