If he means a Henry type of machanism, then, no, HVA never made any.
They made a Martini-Henry rifle, but I realy doubt he would find one here, not at that price, anyways.
The other "lever" guns they made were Clef-Serpent, Roux, English (or, Anglais) and Lefaucheux types. Those were either shotguns or Cape Guns. The only common mechanism is the Lefaucheux type, and the in the Cape Gun configuration they are very rare in Canada (less than 50 for sure).
