Detroit still has all their Thompsons and other "fun guns" I don't see them ever being sold although there are rumors every few years god knows they would make a killing selling them. Not sure I could swing 20k for a Thompson though
The worst part about the DPD 97's most of them were real GI surplus trench guns. They were traded off to century arms and god knows where they ended up. I herd they were only paid $85 a gun in the early 90's
even then GI trench guns were worth 1k apiece. They also had some riot models and some confiscated 97's that DPD had cut down to riots.
