Having carried out some in depth reseach I find that Aiden Steam Man Molesworth was the first product to emerge from the Captain Molesworth Steam Man & Other Mechanical Oddities Co. Ltd. Having failed to interest the Midland Red in Steam Man propulsion, development work was carried out on a petrol version , the Adrian Petrol Man Molesworth but passengers found the exhaust fumes unbearable, (regret no known pictures existing) However the company continued development and turning to battery electrics in the early 1950's came up with Robot Archie Molesworth Mk I. A prototype was built and extensive tests were chronicled in the Lion Comic of the time, R.A.M. Mk II followed with the addition of a mouth to give audible warning of approach. The success of R.A.M. Mk II led to the development of the R.A.M. Mk III which surprisingly reverted to steam but details of which were kept secret during trials lest a competitor should steal the technology. Just when the company had produced a stockpile and were about to launch this new version, a deal was struck with a Doctor Who who had an unusual mode of transport called a Tardis but which to all intents and purposes looked like an obsolete Police telephone box. The deal was that he would purchase the whole stock to be used as props in a series of BBC television programmes of his adventures. Unfortunately the R.A.M. Mk III having been given computerised brains and not wanting to join the Doctor, hijacked the Tardis during delivery to Broadcasting House and set up their own colony on a spare planet just outside Earth. They set up a firm called the Cosmos Yonder Being Engineering Research Co. Ltd. (C.Y.B.E.R. Co. Ltd.) and renamed the R.A.M. Mk III as the Cyber Man Mk I and vowed to introduce Steam Cyber Men to dominate the the World market in pulling buses and goods vehicles. Thanks to the efforts of the good Doctor this has not yet happened but development still takes place at the C.Y.B.E.R. works and currently they are up to the Cyber Man Mk VI. Those Molesworths have got a lot to answer for.
