lapsub,

Thanks for the compliment on my 9.3.

The rib inscription is:

F. Kneipp Nachf. Otto Seelig, Hofbuchsenm (with the rest obliterated by the installation of the front claw base in the rib)

The rifle was made before German proofing required a date stamp; pre-WWI. I believe it dates pretty close to the advent of the 9.3x74R.

There was an article a couple of years ago in the Double Gun Journal about clamshell action double rifles which featured a 9.3x74R that was almost the same as this gun and by the same maker.

Regards,
