Thanks man, that really helps. I always keep my new reciepts. I even get people I dont know to sign a "homemade" bill of sale just in case. I have bought a couple of guns from people I didnt really know and looked a little iffy. I make them give me a DL to record on the bill of sale.Grettings all from your friendly neighborhood property recovery officer!
All of the above are solid ways to prove your ownership. I would add a few refinements to add to your credibility of ownership.
1. When photographing, get a shot of the serial number (if possible) of the firearm. Include distinguishing marks, scratches (heaven forbid), wear patterns, etc. Look at how well folks on Gun Broker and other online auction document the condition of the firearm. You do the same and you enhance your credibility.
2. If buying from an individual have a brief form, documenting the firearm, and date of the sale. Have them sign it. If they are unwilling to do this, think twice about doing this. You need not have all their identifying information, just their signature.
3. Keep a copy of your serial numbers in a separate location. I keep a copy of mine in my desk at the police department.
4. If there is not a serial number - pre 1968 firearms may not have a serial number and be totally legal. Inscribe your state DL or ID(drivers license or state identification card) number. Do NOT use your social security number. I can track your DL or ID far far better than I can your SSN. Your SSN is federal and I do not have access to that information. The FBI and other federal agencies do have access but they are less than helpful ( having their hands full of other cases) to help me.
5. Receipts are the gold standard. Always keep your receipts. In a messy property hearing, (I've had a couple) the unbiased receipt was the clear winner.
I hope this is helpful. If there are any questions or anyone needs further information, you can always contact me off line via PM or e-mail.
One thing I need to do is take pictures.
