No markings at all. Was in one of those rush modes that I didn't take snaps of the process.
My rough guess during sharpening was this felt like a low RC steel, comparable to a 420 level of hardness, maybe C 52-53. 1075 would be in range for this. Looking for pics I see similar samples of them listed as "vintage cleaver". The rust-pitting are amusingly similar and they seem to be generic sterile productions.
This was fun and I put more hours than estimated. (Doesn't that seem to be the case?
)
