Gentleman,
You have to remember that it is the responsibilty of the FFL to protect his license. If he wants to refuse a C&R license, he can.
The C&R license is a confusing thing. One big mistake people make is a C&R license does NOT give the ability to deal in firearms. It only grants you the ability to collect. Big difference. It is NOT a loophole around having a store front business or hours of operation. You are a collector, period.
If during a review, the ATF determines that you are not collecting, you are "dealing in firearms", you could find yourself in hot water with not just the ATF, but the IRS as well.
Generally, if a firearm is 50 years or older, it is a curio or relic based on it's age. They are not all listed on the C&R list. You can write to the Bureau of ATF Firearms Technology Branch to have a firearm considered for classification as a curio or relic. It is best to submit all of your research and evidence backing up your request rather than leaving it up to them.
Kind regards,
