Just one proof mark, right up top on the barrel just fwd of the receiver.

I was able to get some info today from the Browning/Winchester historian who actually was able to look up an invoice tied to the serial number....., this barreled action was sold to the NRA in March of '97 and shipped straight to Baron Technologies, a company that does all sorts of engraving and customizations for most firearms companies and for groups like the NRA (Baron Tech is in CT close to New Haven, historian said Winchester and Browning have been utilizing their services for many years). Baron Tech did all the polishing, blueing, and gold engraving/plating. From there, the action was sent to Fajen and fitted to the stock. All finished up and delivered to the NRA, it was a raffle prize at a Friends of NRA function.

This jives with the box label that says MODEL 70, BOLT ACTION CENTERFIRE B/A, Classic Featherweight Barreled Action, 30-06 Spfld., 22" Barrel
