Stuart 500 boiler without fittings

Smallest of the Stuart 500 range of boilers, the 500 is 2 1/2 inch diameter and will run the slower-running Stuart engines, notable the beam engine and its derivatives. In good order but missing the burner and backhead fittings - it would be a good time to convert to a ceramic gas burner which is quiet, easy to control and doesn't smell dreadful like the original spirit lamp.
