When steaming a Mamod model, distilled or soft, clean water should always be used. Recently a limited edition version was produced for Forest Classics using an all black colour scheme. The crankshaft and flywheel are mounted under the other end.

In the early s the individual tools reappeared. It is also available in a distinctive alternative paint scheme, with a polished brass boiler and maroon wheels. The boiler needs inserts for the safety valve and water level plug.

The model is largely attributed to Steve Malins, grandson of the founder of Malins Engineers. The same engine block has been used on the larger mobile models. Other limited edition models have been produced in the last decade using blue or black paint work as well of variations of the colours mentioned already. The front part is an empty void into which, in the earlier versions, the exhaust steam was fed through the choke it controlled the exiting steam not the inlet steam.

It is driven

This engine featured a green baseplate. It uses the same double acting piston valve cylinder as used in other recent models, which is mounted vertically under one end of the beam, connected to it using a simulated Watts linkage. It carries the livery of the London General Omnibus Company and carried Mamod adverts in the style of the Edwardian period. The model has red wheels and a blue, green or brown body, with a white quarter-length canopy over the engine and boiler.

It shares the distinctive spoked rear wheels with the Steam Wagon model see above. The line shaft first appeared back in when Geoffrey Malins took on the task of making a set of engines for Hobbies of Dereham, after Geoffrey Bowman-Jenkins left Bowman models. Instead, oil is applied manually to the necessary parts before each run.

The company was unable to

The name was misleading in that the loco was nothing like Stephenson's loco of the same name. Copper piping could be kept. Again, a misnomer because it is based on the De-Winton style of engines, common in Welsh slate quaries. The locomotives used a pair of double acting, oscillating cylinders connected to a rotary reversing valve. However, this depends on if the piping has furred over time and has fatigued from being bent over the years too.

It is driven by a drive band from the flywheel. The company was unable to raise the money went into administration, though it was trading in the black in a few weeks with the new railway sets selling well. It was an unsuccessful experiment and sold so few that it has now become collectable. There were steam engines, toy boats, railways, planes and lots more to look at during the show.

The engines could easily drive several workshops due to their bigger boiler and twin cylinders. Very early tools featured simple flat bases with Meccano-spaced holes. The engine has a double reduced drive using a large intermediate pulley, similar to the flywheel. The smooth canopy top was used for only a few months. Lately other variations of roller have included limited editions in different colours as well as longer boiler versions and also a kit version.

The valve gear is controlled via a second smaller beam. The engines were finished in polished brass, chromium plate and red and green paint. Both models used the same hull which was of all steel construction.
