Type 4000 centre flue boiler

Designed by Stuart Models especially for their "Double Ten" vertical and "Score" horizontal twin engines, the 4000 boiler is a horizontal, gas-fired cross-tube design.

In good condition, the boiler is complete with original manufacturer's instructions, burner and a selection of new Stuart fittings. Produced between 1986 and 1990, typical use was in model boats.
