I remember those days! Cash and carry. No paperwork. Pre-1968 GCA. You could pick one up at the gun store, hardware store, gas station, clothing store, grocery store, saddle shop, kitchen table....
Need ammo for deer hunting? the store would break open a box and sell you three or four rounds...
Then bobby Kennedy got shot and the MSM went berzerk against gun ownership.
I remember barrels of German saw back bayonets. M1 bayonets for a couple bucks. With unissued sheaths.
