Clayws..Please take photos of the the proof marks if you can and post at some point. (I am curious as if there are any Engilish proof marks on this piece. Also curious if the piece has Krupp or Whitworth barrels) Serial number reported to me is 123,2XX...and not being familier with Greener S/N's I presume this to be a Sauer S/N. Action has intergral ejectors...not in the forend but in the action itself...makes this a Sauer that is made from Greeners "self-acting Hammerless Ejector Gun" (Facile Princeps action? Ref Greener The Gun and its Devlopment pg 197) thanks in advance for your help. Jeff
