I was wondering if anyone knew of a model of the Ruston & Hornsby 4wDM? Ive searched the DLS and cannot come up with anything remotely like it. For those who are not sure of what it looks like a photo can be found at http://www.miac.org.uk/ncbdroitwich.htm This little engine was at our local yard for about 5 years. It was blue in colour though Im not necessarily after that specific one, just one of this class. Id be interested if anyone knows if one has been produced somewhere. Thanks
