Help with a rare Navy

William, The disc set into the grip looks poorly done for such a pistol. I suspect the grips may be something other than ivory, like bone? 2 Luger grips in actual elephant ivory would be something different to say the least. Horribly expensive and possibly illegal to own. Yes, if you can find out more about this pistol it would help with research and record keeping. Thanks for showing it!
