The Q&A on the ATF site says that whatever you can do with a C&R you can do with a full dealer FFL.
Since a licensed firearms dealer may legally deal in curio or relic firearms, is there any reason why the same person would need both a dealer's license and collector's license? [Top]
A person who deals in curio or relic firearms and holds a dealer's license is not required to have a collector's license. A collector's license enables a collector to obtain curio or relic firearms interstate. A person holding a dealer's license may also acquire curio or relic firearms interstate.
