'M' on Lifter Twist Barrels

[Breck Gorman]

I’ve seen Four “M” stamps on Twist lifter barrels made during the time that John Blaze was producing barrels. One of those Four was a 20 gauge!
It’s pretty well accepted that the Laminated “P” stamps were made by John Blaze, but I’ve searched the documentation and have not found anything that the “M”Twist barrels were domestically made. But it makes sense. It’s a very different pattern than the other twist barrels with “T” and “U” stamps. It is much plainer in figure with less iron and more steel than typical Plain, Stub and other twist patterns.
