Tom:

Are you looking for marks relatively current or pre-WWII? For current there's a British(Proofhouse??) publication entitled "Notes on the Proof of Shotguns & Other Small Arms" 5th Edition/November 1993(I'm sure there's a more recent edition). And is available from GGCA( http://www.germanguns.com ) as B066 - http://www.germanguns.com/books.html . Out of print is Wirnsberger's "The Standard Directory of Proof Marks" for up to the 1970s and GGCA sometimes has it.

Kind Regards,
