Default Irwin Peterson Barrel Question

I have Irwin Peterson 17778XX it has a Marlin barrel looks to be original to gun. I know more than underwood barrels were used. Many proper IP parts on the gun if not proper what should it be. Had the gun a long time 35 or more years.

Think IP (see WB Pg.418) only used Inland, S'G', Buffalo & Rock-Ola barrels.

In that serial number range, I would think a 2-43 through 6-43 Underwood barrel might be the most commonly encountered for an original barrel on that serial number. I would look closely at the proof mark on the barrel to see if that indicates an original IP / S'G' assembly. I haven't heard of a Marlin barrel (presume undated) being on an original IP. Let us know the position of the proof P stamp on the barrel (how far back from the muzzle) and how tall the proof P is. A picture of the proof P would help also.

The P is about 1/8 tall and located 5 1/2 inches from the end of the barrel

No Marking on sight. Looked carefully on receiver no signs of rebuild marks. I think the odds of finding a marlin barrel on a Irwin Peterson rebuild would be great, This has puzzled me for years. Irwin Peterson worst receiver mated with marlin barrel worst barrel maker this is worst of the worst so I guess it somewhat unique

Is there anyway for you to post a picture of the barrel proof or proofs? My thought is that it will be the Marlin proof P, but a picture would help. Also, try and post a picture from around the back of the front sight and the top too, if possible of course. Thanks

Marlin was not listed as a supplier of barrels to IP or to S'G'. IP received 50 barrels from Rock-Ola in Nov.-Dec. 1942. 60 barrels from Underwood in Nov.-Dec. 1942. Then 3000 barrels from Underwood in January 1943 and 1430 from Rock-Ola in February 1943 as listed in W.B comes home.
