64204-1 = TNW 1919A4 in 30-06
64204-2 = TNW 1919A4 in 7.62
Same company but with an earlier name (Northwest Imports) had a different set of FRT numbers, 45004-1 for 30-06, and 45004-2 for 7.62
I only have an older set of discs, so there may be other manufacturers of the 1919 semi auto now recognized by the CFC.
