For years I have looked at the barrels and I have always seen the frame size,ie,1, 1.5, 2, 3, ect. I just picked up a "P" grade with Parker steel barrels and it is marked 12? Can anyone provide some insite into this marking?
Thanks bill

Half frame.(edit: this was supposed to be a question, not a statement of fact.)

The PH-/PHE-Grade was several years discontinued before the 1/2 frame came along. The gauge was often stamped on the bottom of the lug as well as the frame size as on this 0-frame 20-gauge --

Sometimes the gauge is stamped along with the frame size. So that is what the 12 may be. But the frame size would be there also. Or it was removed or worn off.
1/2 size stamps would be stamped exactly like that. Not as 12.

Sometimes, not often, the frame size was not stamped on the lug and just the gauge was... other times the frame size was stamped there but the gauge wasn't. Most often both the frame size and the gauge were stamped. Measure the exact distance in sixteenths of an inch between firing pin centers to determine the frame size.

The action is within a few thousand of an inch of a 1.5 frame. 12 is the only number other than the weight of the barrels.

Bill, what is the exact distance between firing pin centers?
A frame size 1 and a frame size 1 1/2 share the same measurement between firing pin centers of 1 1/16"
1" would make it a 0-frame
1 1/8" would be a 2-frame
1 3/16" would be a 3-frame....

Usinng a dial caliper and an experienced eye ball, I get 1.170
At the widest point the standing breach measures 2.290. sn is
192706, straight stock and 28 inch tubes.

Using an online converter 1.170" falls somewhere between 1 2/16" and 1 3/16" so it is most likely a 2-frame (1 2/16"), there having been scarce few 3-frame 12 gauge Parkers made.

A 2 frame = 1.125"
A 3 frame = 1.1875"
1.170" is thus .045" larger than a 2 frame but only .0175" smaller than a 3.
It is thus about 2˝ times closer to the 3 than the 2.
I guess one could just say "It Is What it Is".
