How many gun owners in America only have guns to collect them?

I cant give you statistics,but I can tell you that as a Collector of Vintage Firearms,I dont shoot my collectors items.That would be like using my comic book collection to light my fireplace.I do own some guns for competition and some for hunting,while the old Springfields,Enfields,Mausers,Mosins,Winchesters,and Colts stay in the safe.
