That's really cool. I don't get the opportunities in my current career to hang around and speak with old WWII vets like I used to in my last job, 23 years ago. I did, however, get to fire one of these on the range:
The M3 Grease Gun. It was over 15 years ago and I only got to fire one mag of .45acp but, from what I can remember, it looked and felt like it was rather cheaply made. By cheap, I don't mean low quality but, rather, it looked like stamped metal parts. It wasn't all that accurate either but it could lay down alot of heavy lead in short order.
