I,m pretty sure that any firearm over 50 years old is a C&R, machine gun or not. Of course, a class III C&R is still subject to the usual restrictions and extra taxes.
RIA Auction company has been selling a lot of Class III weapons lately, and they are almost always listed as having C&R status. But some are not, even though the are over 50 years old.
This seems odd to me. Perhaps one of you with a Class III licence can clear this up .
As far as gun stores and my C&R licence, I have pretty much given up trying to but a gun with it. No one seems to know what a C&R licence is and those who do insist that a gun has to to be on the list in order to be a C&R. NO, no, no! The list is basically a list of exceptions to the 50 year rule. And then there are the idiots who will accept you licence, but still insist you have to fill out a 4473 and run the background check. When you try to educate them they become suspicious that you are trying to pull something.
If it weren't for Simpson's, in Galesburg, that is staffed by people with functioning brains, I would turn in my licence.
