It would be interesting to know from where Scammell obtained these engines. I think 1125cc is the capacity of the thirties Austin Tens, which would have been a good choice, both from spares and durability points of view. Was the 2043cc engine Scammell’s own design? The Standard Sixteen was 2143cc, which caused my whiskers to twitch, but then I realised it has six cylinders, which is hardly English truck material. -- Last edit: 2017-11-04 19:58:24 |

^ Scammell's had their own design and manufactured 1125cc 10hp engine for the MH-3 introduced in 1933. For the 1934 MH6 6-Ton 2043cc engine 15hp I believe it would also be a Scammell design but cannot confirm it. They did also have an option for the 2750cc 45 bhp Perkins 'Wolf' engine but how many were produced is anyone's guess (GWR did have them for evaluation at least). They also patented a smaller Mechanical Horse with an air-cooled V2 engine but nothing to say it made it to the prototype stage; there was probably little interest by companies. -- Last edit: 2017-11-06 14:21:50 |

This site says both were Scammell designs, although unclear there and elsewhere if inherited from the original proposal by Napier which Scammell bought in. The 2043cc was a four cylinder, later expanded to 2090cc as the only choice for the Scarab. |

Thanks for that. Presumably Scammell wanted to ensure the most durable power units they could, so designed their own, they must have been confident in their ability to sell enough engines to amortise development costs when they could have bought in a finished item. |
