Larry,
From my limited understanding; Manufacture d'armes LePage was a large factory. Alot of names get associated with this operation including Nagelmakers, Chauvot, Lepine, Piot, Kaufman & Co and Marchand. Like many of these Belgian operations, the individual companies operated solo as well as in unison. The LePage factory was involved with the production of military arms as well as sporting arms. They seemed to have maintained a retail operation in Paris. I have seen catalog entries for some very high end shotguns.
The LePage name shows up in both the Belgian and French Who's Who. The French Who's Who has an entry for "LePage the grand family of arms". There was a LePage in France at least as early as the 1770's. They also claim a long Belgian heritage.
So, PhyDoc is correct. Judge the arm not the name.
