If you are looking for a drilling chambered in an "American" caliber, you might keep an eye out for a nice Prussian Daly drilling (SD&G made both hammer and hammerless model). Schoverling, Daly, and Gales sourced drilling from Suhl (almost exclusively from Sauer), but chambered them in calibers familiar to US sportsmen - from 25-35 WCF to to 45-70.
It is sometimes amusing to see an auction catalog description of a Prussian Daly drilling where the catalog author assumes what he is looking at is an obscure Eurpoean caliber when, in fact, he has a 30-30 WCF in his hands.
