QUOTE (gijive @ Aug 2 2006, 09:28 AM) I looked at the pictures on GunBroker and although I agree with the assessment of refinshing around the serial number, I don't see anything unusual about the actuator and barrel.
The barrel has a second model Cutts compensator on it which necessitated replacing the barrel. The serial number of the gun is low enough that it probably didn't originally come with that barrel and compensator. It was probably originally a 1921A configuration gun which was sent back to Auto-Ordnance sometime after 1932 for a compensator. Since by then they were installing the second type compensator, it would also require a new barrel with the 3/4 thread size, which differed from the first type compensators.
The second type barrels sometimes exhibit slightlly thicker fins. I believe the gun has obviously been rebarreled, but I believe it is period done and all authentic. The front sight is the proper early profile type also which would be correct for the second model compensator, prior to WWII production.
thanks for the info. After checking the patent date on the comp, I think you are correct. As fas as the bluing around the serial # goes, it has not been touched up by no means. There is still some finish wear there.
