Pete and Daryl, M.A.L. in the Belgium gunmakers language have a multiple meaning. Daryl, I know you have the book" le qui est qui dans l'armurerie Liégeoise" so look at P 148 just above the pictured pistol you can read that M.A.L. is about a gun system from Max Knoll. And in the same book P 163 you can read that M.A.L. is Manufacture d'Armes Lepage. Again the same book P 163 above you can read that it concerne about a double gun "System M.L.A.F. There are more example in the same book but that not concerne the gun you mention.
