A response for records for my gun took about 3 weeks; it was long and detailed and worth every pence. Response came by snail mail and included the entire page out of the record book, as well as a partial decoder of the price code used and a xeroxed pic of a comparable gun to mine from a period A&N catalog(ue).

That said, that was 5-6 years ago, and the record-keeper may have changed.

Good luck
