An Eckernforde Sauer would be post war, so any Suhl type butt plate would be incorrect. The post war Sauers are very good hunting guns and often more fitting current American taste in style and caliber, but are not as "collectable" as pre war Suhl drillings. Consequently, you won't hurt your drilling, regardless of which one you choose. You might contact Larry Schuknecht at Dutchman Wood Works ( Shoptalk@ dutchmanwoodworks.com) as a source.
