Friend of mine's Pop, who is no longer with us, showed me an old magazine from back in the day, where for $10 you could order a Thompson Sub Machine Gun w/ the Drum.

It was a black n white ad in the back of the magazine and they'd ship the weapon in the mail.

I miss that old-timer, he was good people. WWII vet, based AF, knew everything there was about reloading. First time I met him, he handed me his 1911 and a box of color coded reloads to go shoot so we could report back how they did. He would then mass produce the best results for us.
