Off topic but would appreciate being pointed to the correct location. I left a post on AOW forum site but thought the TSMG board would have the answer.
The BATF used to publish a list of C&R firearms removed from NFA registration requirements. It would include certain firearms by actual serial # such as Winchester trapper short barrel rifles. And I understood they update the list from time to time as people write in requesting removal..
I've downloaded the BATFE PDF MANUAL but it didn't seem to have the info.
Been at this a long time ( SOT since October 1971 ) and registered 18 items during the 68 amnesty while living in NC. Seen a lot of changes over the past 49 years...
Thanks to all for your help
