Just to clarify, that .020 - .025" MWT refers to the distal 1/3 of the barrel. Which of course is most likely to get whacked.

Thanks (mostly) to Dave Suponski we have composition data on a few Parker barrels
A pre - WWI Parker “Titanic” barrel - AISI 1030 with low concentrations of nickel and chromium.
A pre - WWI Parker “Trojan” barrel - AISI 1035.
A pre - WWI Parker “Vulcan” - AISI 1015
A post-WWI Parker “Vulcan” barrel - AISI 1030.
A “Parker Steel” barrel was non-standard Acid Bessemer Resulphurized Rephosphorized AISI 1109 low carbon Steel.

Lower carbon (in general) = softer steel. Scroll down about 2/3 here
