Does this qualify for a C&R weapon?
Yes, it is most definitely a C&R. Any gun that was made 50 years prior to whatever the current date is will be considered a C&R.
ALL guns over 50 years old need not be specifically listed on the ATF Curio & Relics list; They are still C&R's. This is something many FFL dealers do not understand.
Also, there are some guns that are specifically listed on ATF's C&R list that are less than 50 years old. A good example would be the Interarms "Parabellum" (Luger) pistols that were imported in the 1970's.
