Any gun that is 50 yrs old or older is C&R eligible. Far too recent if
made in 1966? According to my math 1966 was 50 yrs ago. Now for
those who like to nit pick and play the what if game the questions
about day and month give them lots of ammo. It really comes down to
what a seller wants to do because it's hard to believe the BATF has
nothing more important to do than worry about private transactions
and exact birthdays.
