Mark on Barrel and Receiver

[Dave Southard 0]

Guys - Came across an unfamiliar proof mark on a B-series JSAR; it is a P, marked at the bottom of the receiver and on the barrel, immediately behind the guide collar. Pictures below. Have any of you seen this mark before, or have any idea what it represents?

Never received any feedback on this - have any of you come across this mark?

No "P" on mine in either of those places.

The center bushing looks different...is that how all the later ones are?

Neither my A nor B series have those proofs. My bushings are different, as Dash mentioned.

Interesting. Hadn't noticed the bushing, but just checked it against my no-prefix Johnson and it too is different than this one.

Anyone with thoughts or insight on that?

Hey I am not sure about the P. It could be a pressure test mark. Perhaps Brian, Joe, or the Boss will know when they get back on .

The guide is spaced with a washer to put it in the correct place. I have one like this also, and i believe it to be a Winfield fix for a barrel that was milled to far up the center. Mine functions fine with that guide and washer set up.

Hopefully we can come up with the answer on the P.
