55 dollar grade with Blaze forged barrels

[Pheasant Slayer]

Has anyone tried to isolate the "M" stamp? Meaning, has the members of the PGCA come forward and documented who has this stamp on their barrel flats, year of the shotgun etc.? Is the "M" stamp limited to barrels that were supposedly manufactured by Parker? I noticed in a prior thread John K's lifter is plain twist & he also has the"M". His serial numbers are in the 17200 range. Is it only on Plain twist or also Laminated? Yes, lots of questions. It would seem documenting who has it when it seems to disappear would narrow it down.

Lots of information here regarding American made pattern welded barrels, and those of Parker; mostly courtesy of Brad Bachelder and John Davis.
Dean's Parker made Laminated Steel barrel is also shown

We now have Twist Lifters with 'M', 'M +', and 'M F'
IMHO there is nothing special about the appearance of the Twist pattern to confirm the maker. The Parker made Laminated Steel pattern is unique.
