OK, I can add a little bit to that. The Super AMD had a direct start diesel of 264 cubic inches and a twelve volt electrical system. The AW-7 Diesel and A554 Diesel had the same arrangement. The 12 volt start was really insufficient, the diesel engines were difficult to start in cold weather unless the batteries were both fully charged and in good condition. The Super AMD had the second battery under the seat while the AW-7 and A554 Diesels had both batteries in a long box on the near side of the engine. The direct diesel engine suffered from considerable vibration which rattled the chrome plated badges off the engine hood and destroyed the instruments on a regular basis. It was, however, a powerful motor. I learnt to drive tractors on a 1955 AW-7 Diesel; it was a tractor which happily worked a 14 disc plough in heavy clay soil.
Also, a note on the Victoria Museum. They have some lovely photographs of old machinery and some great scale models of Sunshine Massey-Harris equipment. The Museum is on Rathdowne Street in Melbourne and well worth a visit if you happen to be in Australia and further happen to be in Southern Victoria. You do have to be careful with the information supplied with Museum photographs; it is sometimes a close guess rather than verified data.
