Commerical 9mm

[Jasta2]

Little info to post here, but this is what I know from a VERY fast look over it in poor light. I was leaving a fellows place when he brought out from what I could tell was a commercial in 9MM. Only looked at it for a min. ( not by choice) What I noticed, near mint finish, could see no apparent buffing. Owner said it was never refinished. Outside the finish, the chamber was blank, DWM scroll on link, nitro proof on receiver ( lightly struck ) matching 4 digit number on frame and barrel with the last 2 digits on the rear of the toggle. No other proofs marks noticed. Owner said it was matching. I'm not quite sure where other matching numbers would be stamped on a commercial. Where else should I check? Wish I had the time to inspect it more and have a camera. I take it must be from the postwar era, but not sure on that. Maybe from info I've posted you guys might narrow down the era. In any case, he is only asking $1,000. A shooter in that condition would be worth that much. Going to buy it Monday. Will post some pictures.
