As is this
I found a
1950 WRAC catalog on-line
https://nhba.yale.edu/assets/uploads/fil...0-Catalogue.pdfThe Model 21 & M12 are of course listed with "Winchester Proof Steel" but there is now no mention of "Chrome Molybdenum"
The
Model 37 barrels are listed as “Winchester proof marked”, as are the barrels on the
Model 97; which when introduced until at least the 1930s had “rolled steel” barrels. This is likely Winchester Standard Ordnance Steel “cold rolled” Bessemer/Decarbonized steel.
I could not find that the M97 was ever offered with Nickel Steel.
In the same catalog the
Model 24 is listed with “high quality steel” barrels.
