Commercial .30 --what can you tell me about it?

[phoneman517191]

DWM on top of toggle. 8848 on front of frame below barrel. And below this--looks like an arrow pointing to this number of 8848.The bottom of the barrel in front of the receiver also has 8848 and above that --a crown with a N below the crown.And a character that looks like an arrow below the 8848. And a 48 on rear of toggle below rear sight. A faint N on left frame in front of side cover above trigger. Gesichert behind safety lever. The trigger has a 48 on it when the side plate has been removed. The back of the side plate has a 2 on it. There are no numbers on the other parts--not like a military issue. Wood bottom magazine . Stock lug on the rear of the grip frame. Looks to have been reblued--the rear of the frame is a brown tint around the safety lever. Circular machine marks on frame near the rear pin of the toggle.Ad light machine marks around the disassembly lever and above the trigger on the right side of frame.

Is this a Commercial 1920 or 1923? Sorry about the pictures--not as clear as I hoped.
