Technical help from Rudge experts...

Sam E Radial is on hand to answer those nagging technical questions like "I have an aluminium chaincase outer with 4 screw holes and no projection for a dynamo -is it correct for my 1929 Ulster?

The 1929 Ulster was the first Rudge to have a 2 piece aluminium chaincase. Not a true oil bath, it was also the first to be mounted to the engine. The 1929 outer chaincase M2529 x 1 is distinguished by having 4 off 1/4" holes through which screws attach it to the inner. The 1930 outer chaincase, from the same casting pattern and listed as having the same part number, had the 2 forward holes enlarged to 5/16" where screws passed through it and the inner to attach to the engine crankcase.  If your cover has 4 off 1/4" holes, then it is correct for 1929.
