Ron Wall?
I'm not sure, Louis. I'd think it'd be marked, in that case, though I don't know if all of his castings are marked. I have a couple of foot figures, and they're marked under the base with "R. Wall" and a year. It's a soft marking, not engraved into the mold, but as if it had been scratched into the base after extracting it from the mold. But that's as good a guess or better, than any we've come up with so far.
Prost!
