NFA arms, even if classed as C&R arms, nust still be transferred, and the transfer tax paid. It can be transferred directly to you without going thru a class III dealer, but tax man still wants his share. Translation- you want a nice 1928 Thompson smg. Being made in 1928 it is C&R based on age. Being a machinegun, it is also an NFA arm, and you will need to pony up the $200 tax.
