The 'LLH' of Laurent Lochet-Habran has been found on steel barreled Smith and Hunter Arms Fulton and "Ranger" for Sears, Lefever, Fox, Ithaca (esp. the Lefever Nitro Special), Baker (may be marked "Nitro Rolled Steel") and Folsom Crescent guns ("Fluid Temper Steel")
BOTH 'ACL' - Acier Cockerill Liege - and 'LLH' are found on Belgian guns, Crescent, and a Baker S grade
I believe Laurent Lochet-Habran was both a maker and exported, and have no knowledge of a relationship with Pieper.
I wish we knew all the Belgian exporters and U.S. importers
Whose partial mark (on left) could this have been!?!
More infro here, but for the record I know nothing about that new fangled fluid steel stuff
