Rimfire ID needed


#1

Most of my notes for Rimfire cartridges in the low letters have been lost and I have one I am needing a company and country ID on. I thought I remembered it as being from Belgium, but not sure. Picture below. On either a .22 or a 6mm Flobert this one.
Thanks

My guess is the gunmaker, H. Alard fils et Cie, who had a cartridge manufacturing plant in Maastricht, Netherlands. He trademarked the A in triangle in the late 1890s.

But the pinfires of his I have do not have the circle. So I am not certain at all.
