antique brass & copper camp stove vintage alcohol stove for camping backpacking

Antique brass and copper portable camp stove with finger ring. The brass and copper have been brightly polished. We believe this is an alcohol stove and we're not sure of the maker (maybe Landers, Frary, Clark?). The underside of the fuel tank is marked with patent dates from 1906.

This stove measures about 4 1/2" high and 6" across the top and 6 1/2" across the bottom.
