I picked up this M&P at the gunshow today. My guess at age is around 1921 - 1922 or so. The serial number is 3890xx . Just guessin at the year. The pictures do this gun no justice at all. It is as clean as they get! I would rate it 97 to 98% . I have not given it a good cleaning yet but the blue looks as good as the day it was made. There is a slight drag line and the slightest of wear at the muzzle but that is it. Looks like it just sat hidden away all these years. I wish I could get better pictures maybe I will try again after it is cleaned up. These pictures are probably good enough to give you an idea of how nice this piece is. I know there are alot of these guns out there , but are there many out there from the 20's in this condition?
