National Engines

This might seem a bit obvious but have you tried contacting Geoff Challinor at the Anson museum for more info,probably the most informed source on these engines around.

The B type was built from 1933 to 1959 ranged from the JB of 5" bore to the TB of 11" bore, they have a Russell Newbery type combustion chamber.The smaller engines had CAV pumps and the larger engines had a National made pump.In 1954 production was transferred to McLaren's. If you have the bore size I can tell you what type it is.

Thanks for the info. From a previous reply I gather your the "main" man for these engines. I have been told that the serial number is on the Breach (where ever that is) Are there records of the engine production, year of manufacture etc that the serial number can be used for. Otherwise once I have the bore size is it possible to age the engine. Would you know of where I can obtain the hand book (erection and maintenance) for the B series ? When I have time to start looking into the engine & possible problems I assume any parts required will have to be one off made parts, is there anyone who specialises in these ? Any help would be appreciated as I dont want to head in the wrong direction.

Cheers

I expect you are all aware but,

Russell & Newbury (R&N) still in business at Daventry where they still manufacture R&N engines and also rebuild Nationals. They are a bunch of enthusiast engineers of the old school and will probably be most helpful.
