Very astute Ken61 & that's what is great about this site. I think most of the info was composed from an article by GGCA/Dietrich Apel(note Larry B. Schuknecht is the custodian so I wonder how Dietrich is: http://www.germanhuntingguns.com/). Anyway, the engraving is just lovely & from the few images it would date post 1912.

Cheers,
