I just inherited one also.Mine has the 2 inch barrel.The only problem with mine is the bluing which is only 40%.Mechanically it is pristine and had only been fired maybe 2 times.The value would have been 600.00 to 700.00 if bluing weren't so bad.As is mine is worth 400.00 dollars.I had to order the rounds for it and they weren't cheap.About 90.00 dollars for 100 rounds.I think mine was made in the early 1920s as my Grand father was Chief of police in Macon GA in the 1920s and this was his backup gun.Don't know if this helps or not.
