Several of the Remington RB97 Rolling Blocks I am familiar with were supplied with nice, felt lined hard cases. Also included was a signed certificate indicating the builder, the build date and confirming the serial number.  These three identification items are hand written in ink.  Nice touch!
A while ago I acquired another of these fine rifles and it was accompanied with the Remington hard case and certificate.  Unfortunately, the serial number on the certificate did not match the rifle in the case 
I'm looking for the owner of RB970046; I have your certificate 
If you have a non-matching certificate; it might be mine.
Even if you don't have mine, I'd gladly surrender the one I have to the proper owner.
Mike.
