Burns nice. Only thing cast into bottom is "patent's are applied for" no other markings. The tank fill hole doesn't look threaded so possibly never was a cap maybe just some sort of plug.
But the tank and burner is same with Landers, Frary & Clark, in 'America/Other Brands/' ....CCS Gallery.
Not the same as mine, that is a Manning Bowman, not Bowing as I wrote in earlier post. But probably a number of manufacturers produces stove of similar style. Bo
