I knew plenty of WWII vets back in the 1950's/60's..................I saw more "things" hidden in the rafters that you might believe.............west of the Mississippi and in the south, is where most of these WWII "things" are located today,........... DC included. But every so often, like the Nambu, floor boards are pulled up after granddad died.......... and voila.................black market sales proliferate.
Unbelievable stuff..............back before Hughes.
Gunshow network...... was like the French Resistance back in the day....ATF knows it but the horse has left the barn on most WWI stuff now.
It was estimated by others, that the number of registered "stuff" ,is like 10% of what really exists, and that does not include the converted AR's in the free states.
Americans are likely, war ready.
NRA back then, stood for "National Resistance Association". Believe it.
