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.

Thanks Drew for the information. I will surely read through it. After some searching I have also read that Blaze may have not worked directly for Parker but, when Wesson went out of business he was supplying barrels to them. The article I read said Blaze may have been supplying barrels to other companies as well. It would be great to see what information Breck has. He did mention a correlation with the "M" stamp. These barrels came from somewhere!

To the best of my knowledge, Parker made barrels were Laminated Steel and were stamped on the right barrel flat with a P with a broken left side of the foot of the P and were on the forward section of the flat where we customarily see the stamp for the type of steel the barrels are made of.

The M in reference to Blaze, the maker, is brand new to me, althougb I’ve seen the M stamp a few times previously.
