A. M. Schnetzler?

I have come across a plain 2-piece carboard box, with dividers, and inside there are 50 32-40 new, unprimed cases, Western h/s. On the top is the name A.M. Schnetzler and nothing more. Has anyone come across this name before?

I suspect he was a jober, wholesaler, etc.

He could also have “just” been the box owner and wanted to not loose it?
Name in print, rubber stamp or hand written?
PS not heard the name before

I don
