Thanks to you both! My guesses were OK (this time), except for the "Bochumer" name.

My only association with "verein" is a fascination with the "Turners," a largely forgotten chapter of American shooting history.

I assume the caliber marking in English and the "Made in Germany" show that this gun was made for import into the US from the get-go.

Were .30-30/7.62x52R rifles ever made in Germany for European use?
