Jim, Without any evidence otherwise, I guess it is possible service engines were un-numbered. Seems like it would be awfully hard to keep track without something though--at least to document for warranty purposes or running changes to say nothing of DMV requirements when engine numbers were used.

We are missing page 6 in the last Studebaker bulletin (#350) where they discuss replacement S8 engines so don't know if anything was mentioned. There was an early bulletin saying mechanics were to stamp numbers and gave some instructions. IIRC, a couple of years ago one poster had a title with strange numbers or information he couldn't document. The motor number he posted had extra info which I believe we speculated was indicating a replacement.

At any rate, you have looked in the spots they normally were stamped and I don't know any other places to suggest. I don't remember hearing of one but does anyone know if they had anything like the later Utica number in some obscure place?
