1-9/16", hmmm. Did you mean 40mm? :P

I agree with Gary, you need to buy more planes now, so that you have
more chances to match those lonely irons! :)
The more you buy, the higher the chance....

"Sohne" means "Son" in German. Everything points to German origin.
Henry Boker is a well known German manufacturer.

Oh, just found a wikipedia page about your "Steiner & Sohne":
https://de.wikipedia.org/wiki/Jos._Steiner_%26_S%C3%B6hne

I used Google translate, as this page doesn't seem to be available in
any other language than German.
"Jos. Steiner & Söhne oHG, later also known as Laupheimer
Werkzeugfabrik AG, was a company that continuously existed from 1859
to 1991 in the production of tools for woodworking in the district of
Biberach in Upper Swab."
