Reminds me of a Saeco.

But all of theirs I've seen were stamped with their name too.

Not SAECO. Dimensions smaller. I compared it to one.

Saeco dies are threaded on the bottom, too.

Hope this helps.

Fred

Not all SAECO are threaded.

If I can find the make, I'll use em for PIF, as I only have Star and Lyman machines.
