Rob,
You are correct about the C 7 R, except there is a mis-conception that a c & r is exempt, that is incorrect, it can only be shipped to a FFL or a C & R FFL.

The antique can be shipped w/o and FFL, I did not ask the auditor if the gun hand been altered, is it still and antique?

A good question. I think I will call the guy who audited me and find out.
