NSN (no serial number) is a legitimate log in option for FFL holders in recording guns in their book. Griffin and Howe, Sedgley, and other Springfield sporters with a stippled front bridge are routinely entered on 4457 forms by whatever number is available, including NSN.

Yes I've been logging them in that way for almost 40 years. Was just wondering if in some of MP's research he may have come accross something that indicated when the Gov'mnt decided it wasn't legal anymore to remove, move, modify or alter an existing serial numbers. That would have changed G&H and the others sporterizing modification practices re: the ser#'s. I thought it might be somewhat helpfull in dateing some of the custom pieces if a year was known and the modifications were present or not.

GCA'68 is eccentially a rewrite of FFA'39. The only major thing that the '68 law added re:ser#'s was that 22rf long guns and all shotguns must have ser#'s. Everything else mfg in the USA before that time was already required to be ser#'d. But I can only find such language back as far as the 1939 Fed law.
