Early Radius fuel caps. I'd been looking for the correct cap to fit one of my Radius 42 stoves and have accumulated a couple extra caps that don't fit anything I have. Finally bought a stove that was missing some parts, but had a cap. The lower, right hand cap is correct, it has the Ltd. I'm using one of the incorrect caps for the parts stove and moved its cap to one of my keeper 42 stoves. Duane
The two in the middle are for lamps from about 1934 to 1937. I have no idea what the left hand one is for. It is quite a large opening.
