Bought a second-hand 1911 that you think was customized by Harrison Design? Want some provenance to show what was done and to authenticate the custom work?
I will search my records and provide you with a copy of the original invoice with the original customer's info redacted. I am not able to search by serial number, so it takes some Detective work to find your record. I charge $50 for an invoice search, $100 if you want the invoice and any original pictures that I have. If I can't find anything, I don't charge you.
