It is my limited understanding that the NFA items that could not be transferred to private individuals or corporations because of the Gun Control Act of ‘68, but were transferred to Government Agencies, are the Pre Samples that had had a change in Transferable status. But the items that were imported as Pre May Samples that were not transferred to a Government Agency are still considered Pre Samples. So an HK MP5 SD that came into the country in 1984 that was transferred to a Police Department would have the change in status to transferable. A WW II Thompson M1A1 that was imported back into the country in 1970 as a Pre Sample, but had not been possessed by a Government Agency, is still considered a Pre May Dealer Sample.
There were a bunch of HK 94 carbines imported in 1991. Because these carbines were imported to the State of California, even though they didn’t comply with the ‘89 import ban. But since the 94s were imported for a Government Agency the import restriction was waived. It is my understanding that both the importation of “Assault Weapons” and the importation of NFA items simply restricts importation. Once these items are imported for a Government Agency, these restrictions are no longer in effect and the Government can dispose of the items as they see fit. This importation limit has been satisfied by the Government Agency. But this Government Agency satisfying the importation limit restriction is only for those items. Any other items would still have the importation restriction. That is why it is only items that were possessed at one time by a Government Agency, has had the restriction in transfer removed.
