The backhead has water gauge fittings, clack valves and regulator; a pair of spring type safety valves are fitted.\u003c\/p\u003e\u003cp\u003e    The tender chassis is largely complete, the tank is part-built in brass, with a pack of profiled brass for the cab.\u003c\/p\u003e\u003cp\u003e    Complete with 24 sheets of drawings.\u003c\/p\u003e\u003cp\u003e    Despite efforts to save 60145 \"St Mungo\" - then only 17 years old - all 49 of the original class were scrapped by 1966.
