GECO is short for Gustav Genschow & Co, they formerly retailed all sorts of hunting and shooting gear. Much like Orvis does today and sold guns marked with GECO that were sourced from other makers. I have seen them with German, Belgian, and Italian proof marks.

Ammuntion is still sold under the GECO name today.

Mine's a tale that can't be told, my freedom I hold dear.
