Anybody ever seen one of these?

When my grandfather died several years ago, I inherited all of his guns, and among them was a really odd, mostly unmarked single-shot rifle. I recently started researching it again and have identified it as a Belgian Flobert rifle in .32 cal. Has an octagon barrel and a "trapdoor" breech. Not particularly valuable, in monetary terms, but cool nonetheless. Mine looks mostly identical to the one pictured below, though not in useable condition (even if it was, most of what I have read said it's not save to shoot modern ammo in them - not sure if you can even get .32 rimfire anymore?) so it will mainly be a wall-hanger.
