Thanks for the information. I think is has the German Eagle proof mark. I don't know how to post pictures on this site or they would already have been posted. There is a 142 stamped on the flats. Could have been made in 1942 but the workmanship is very good. I thought it was made a bit earlier. It has 28.5 inch Krupp steel barrels , didn't figure a war time nation would use the best steel in shotgun production. I might add that all the serial numbers match. I am curious why there is more interest in German gun and less in the Spanish ones.

Regards
