Finely engraved Belgium Revolver A nice little pistol made by Edunoulin & Co Liege Belgium. (French-speaking region of Belgium) Although it has no date I believe it dates to around 1890 based from the style of engraving. It's about a 25 caliber or 22 mag. Trigger folds in. hammerless design. Makers marks are all over this gun! 6.5 inches overall. 2 5/8 inch barrel.
