The Mamod Showman's Engine is an enhancement of the TE1A. As expected on a Showman's engine, there is a dynamo mounted on a bracket in front of the chimney. On full sized engines, this is fixed to the smokebox but on this model, it's attached to the canopy; presumably because the canopy was easier to modify than the smokebox. The canopy is longer than that on the TE1A, in order to accommodate the dynamo. There are also twisted brass supports around the dynamo but not at the rear. Another enhancement on the TE1A is a set of dummy steering chains and worm drum. It's a pity these don't have a steering wheel to operate them! The flywheel is slightly larger and has a groove in the rim to fit a drive belt for the dynamo. It is plain unspoked, like the kit version of the TE. Livery is maroon boiler and scuttle with yellow wheels.
The boiler appears to be the same as the TE1A, 1.75" diameter x 6" overall length, presumably with the same empty section at the front. It has a sight glass at the rear end, whistle, safety valve and steam output, with no dome or regulator. The burner is a standard tablet tray.
The steam is fed directly to the standard Mamod mobile engine frame with a single oscillating cylinder. The cylinder is 9mm bore x 20mm stroke. Exhaust is fed to the base of the chimney. The engine is not reversible. The dynamo is wired to a set of LEDs mounted along the canopy edges.
The model as a whole was not designed with ease of use or access in mind. It is in mint condition so I shall probably keep it that way, as one of my few shelf queens.
