I'd hazard a guess 1830 - 1842 but the more I stare @ the info, them more I'm inclined to believe it was one of the Brothers LePage who was trying to scratch a living as an arqubusier, advertising vaguely on his wares in an effort to abstractly promote his wares as possibly being that of the main LePage, Arquebusier Jean André Prosper Henri Le Page? So I highly suspect Liège sourcing.

Cheers,
