Somsou & Bruneaux

The other day, on a non-ebay antique site, an interesting cork extractor had just been put up for sale.  As I looked closely, I saw the markings Bruneaux and S.G.D.G.  Or, at least most of what was supposed to be Bruneaux.


The Somsou & Bruneaux patent dates to 1863, and has shown up (not often) but with a variety of handles.  A pretty neat cork extractor, but given it is French and not American, anyone want to make a trade?
