I have a picture of the barrel lugs that looks factory original. Under one barrel it clearly shows a JG in an oval and 3 in. MAG. the middle has a 12 sideways 2; the other barrel has a V in a circle, HT over A and a large 4 smaller 2.


My best guess is that the "3 in. MAG." was stamped on the barrel flat by the gunsmith that hogged the chambers out to 3-inch.

If you want, email the picture to AHFCA@comcast.net and I'll post it. You still haven't told us the serial number of the gun.
