I'm looking for knee grips for an Excelsior... has anyone got any or know where I could get them?

That engine is a replacement. The engine number prefix identifies it as an engine first fitted to a 1950 James, not an Excelsior. According to my local police records the appropriate engine number prefix for your model Excelsior was 905/***. This is not surprising as for many years it was far cheaper to buy a used Villiers engine from a wreckers than to spend money on rebuilding a worn out one to new. Plus of course if you did lash out on a reconditioned exchange unit no one cared about the original engine numbers anyway. This was a daily rider working bike not anything fancy.Hi 33d6, I need a dating certificate for this bike, any ideas?
As to the gear ratios, Villiers identified the change over to ratios more usable on the road by stamping a 'D' suffix after the engine number. This also identifies updates to the crankcase compression seals. You can see from your engine number that both the original engine and the one you have now came from the factory with the wide ratio box but who knows what has been done in the last 60 years. If you want to know all the technical ins and outs buy yourself a third or fourth edition of "The Villiers Engine" by B E Browning and published by Pearsons.
Welcome to the wonderful world of Villiers.
Cheers,
