Should be 1095 carbon steel I think. Cool old Queen Steel knives, great find.
IMO the knife should be 440C.
Queen was first American cutlery to use SS AFAIK.
Also, when stamp reads Queen Steel or Q Steel, it is generally always stainless. Exception would be newer models with D2 or special runs. They used to use 440C. Then later switched to 420.
If it said Queen City Steel, that would be 1095......
