I just want to see these classic guns. I photograph all my guns when I get them so I can either schedule them on my insurance or just make a record of ownership. I keep receipts and all manuals and other paperwork that comes with a gun.

When I sold a gun, before the days when all private sales required a background check and FFL transfer, I had the buyer sign a bill of sale and attest to the fact that he could legally purchase the gun, and made a copy of their drivers license. I've kept those for just about every gun I've ever sold, along with the photos of the gun, just in case one shows up at a crime scene.

It's just wise to photograph all your guns, to include the serial numbers.
