What year fordson power major?

On the left side of the diesel engine above the
injector and below the lines that go into th block is stamped the following S434957

Anyone have any idea what year this is? Any hints
where else I might look for a serial number since
this does not seem to match the list of Fordson Power Major serial numbers found at>Link

Thanks,

Brian is correct, your engine is not original to your Power Major. Fordson 220 cid power plants were used in a variety of applications, including being sold to other companies such as County, Muir-Hill and Roadless for conversions. An engine, drive train, axle assembly sold to these companys were referred to as skid units. The engines in these units had a serial number beginning with S. I have never discovered any reputable information on the date of manufacture legend for skid units coming out of the Dagenham assembly plant. County Commercial Cars LTD had records of their skid units delivered, but the records were destroyed in a fire in the 70's. I believe the Fordson Power Major was introduced in late 1957 as a 58 Model and were continued into the early sixties. If your unit does not have a tag on the front of the firewall just in front of the battery... it will be difficult to ascertain it's year of manufacture.
