I can't find any info on the Wilh Eblen Cannstatt rifle. Google searches seem to replace "Cannstatt" with "Stuttgart" and this rifle has "Wilh Eblen Cannstatt" engraved on it. Any suggestions or info.?
Nope, 4mm is what the rifles are listed as being in numerous auctions. Technically it was 4mm Lange4mm is like 20 caliber.
i believe PHD meant 40 caliber, which was a popular target shooting caliber.
easy enough to tell, look at the muzzle if a pencil won't come close to fitting it's a 4 mm, if your little finger will poke in there it's most likely a 40.
you have what would be called a scheutzen rifle.
where targets are shot free standing [standing up] usually at 200 yds.
