"German" marked on there probably means it was a commercial U.S.
import rather than some oddball war booty. 7/8" was pretty much the
standard scope tube size pre-war. There were a few 3/4" ones. Split
rings were pretty much the rule, too, I've got an old period
gunsmithing book that tells how to get them onto the scope, after all
the external bits were removed. Involved a business card or matchbook
cover(remember those?) in the split. Had to be careful that the sharp
edges didn't dig into the scope tube or it would have to be
reblued(rust method recommended). A guy had to REALLY want a scope to
get one on a rifle in those days. Has it got coated optics? The
Gemans pioneered anti-reflection coatings pre-war. You'd see kind of
a bluish tint on the lens' surfaces.
