Mamod Minor 2


This is the last version of the single cylinder MM2, made for just one year before it was replaced by the SP2. The first version of the MM2 was a twin cylinder horizontally opposed type but few of them were made and are now very rare. The model was reintroduced in 1948 with a single cylinder so that it became similar to the slightly smaller MM1 which was updated about the same time. This design was updated several times, culminating in this version with a raised base, engine frame riveted to the boiler, mazac flywheel, sight glass and solid fuel tablet burner.

It is an overtype engine with everything mounted on top of the 1 3/4" diam x 4 1/2" boiler, including the 5/16" diam x 3/4" stroke cylinder, 1/4" safety valve, 2" diam spoked mazac flywheel and the purely cosmetic dummy chimney, which doesn't even cary the exhaust steam. There is a standard Mamod water level sight "glass" in one end of the boiler. It should have a solid fuel tablet burner but that is missing.

When acquired, the paintwork had been redone in the wrong colours at some time in the past and was already peeling off in places. The last photo on the left shows the engine in this condition. I have since repainted the base and firebox in VHT paint.
