Technical help from Rudge experts...
Sam E Radial is on hand to answer those nagging technical questions like "I have been offered a gearbox for my 1930 Special and the seller has sent me some pictures. It has Rudge Whitworth cast into the rear cover as I would expect for this year. Can you tell me if the gearbox is suitable from the numbers?"
I certainly can! Unfortunately, although a 1930 gearbox, this is NOT suitable for your 1930 Special. The numbers show a small N suffix. This was used by the RW factory in 1930 to identify gearboxes destined for the JAP 250cc as these gearboxes continued to use the 'N'arrow teeth form. You will have to confirm this with the seller but it is unlikey that the internals have been changed. You may also note that, despite what the 1930 spares list says, the 250cc gearboxes DID NOT have the external kickstart stop. Now theres a thing!
