Mamod TE1a "Genesis" and TE1 Traction Engines

My first steam engine purchase was TE1a “Genesis” in 1970 for £17-10s-0p (£17-50p), how times have changed! The tyres are a recent addition.

At the moment I have a total of four TE1a and one TE1 version of this engine. The TE1, though almost complete, needed a little TLC. It is featured in my Restoration Projects page and is dated approximately from 1965 to 1967.

Mamod Short Boiler Steam Tractor

This is a beautiful rebuild of the TE1a using a shorter boiler and was built by STEAM4FUN. Another great dealer. The final build has produced a very handsome engine.

Wilesco Traction Engine

Great engine for running static or mobile. I particularly like the gear engage / disengage function.

Mamod Centurion Tractor with Living Van

This shows my Mamod Centurion Tractor with a Living Van and accessories.

Mamod SR1 and SR1a Steam Rollers

I have an example of both the SR1 and SR1a versions of the roller. The SR1 engine does not have the reverse lever as fitted to the SR1a. Note the early version of whistle on the SR1.

Mamod Brooklands Tourer

OK, it won't outrun a Ferrari, but it's better looking and has a quieter engine!

Mamod Steam Wagon SW1

I have two colour variants of this smart wagon, blue and green. They are great representations of Foden wagons!

Mamod Trailers

These are the Logging Trailer, Open Trailer and Water Bowser.

Mamod Home Built Marine Engine

This is a home built marine engine using a Mamod SP type boiler. It comes complete with prop shaft with universal coupling and propeller.
