" This is number 14/100 of the special edition TE1V produced by mamod for forest classics. The model is pictured with rubber tyres (bought separately) and without the additional black canopy or brass chimney cowl supplied. The model is the first piston valve model and features the new mamod piston valve steam engine and a new boiler. The boiler features superheating via 2 tubes which take steam from the boiler and circulate it through the burner and back in to the boiler. I have been informed that this was changed to a coil configuration in the later official ""challenger"" and ""centurion"" models. The model is much more controllable and has far more torque than a TE1A. It is possible to slow the model down to a crawl. By far my most used engine. "
