Ibby, are you talking about a license to import prohibited firearms, or prohibited devices? If you're talking about the latter, no individual can possess one. Only a business can, hence the term "Business Firearms License". And individual can own a business and the business can possess the license, but the individual can't possess the license.
And a 12-class license is even more rare, and getting more rare each year.

Democracy is two wolves and a sheep discussing what's for dinner.
Freedom is the wolves limping away while the sheep reloads.
Never confuse freedom with democracy.
