Mick I imagine they are the same. You could ring Jeffrey and ask him. I just took this picture of my repro grips with piled arms.....But I do have a real BSA saddle.

Ron and Michael, In fact they are not the same, the folding bicycle has celluloid grips, and the MK V and MK V* have "Grips Handlebar, Rubber" Part Number 10218.
The postwar parts list also mentions "Rubber"
But you might aswell do with only one!!!
Sorreeeee,

Yes, they are celluloid over cardboard originally, and break easily!
Here a picture of a postwar MK V rubber grip, will see if I can find more info.
Do note that on this website, this particular bike is a postwar one!

OK, here we go on the grips, first a brownish plastic one, postwar I think?
Then a nice rubber one, make "Britannia" slightly postwar??
And last a rubber one that looks like the WW2 model, no make or anything on it, and quite old!
Cheers,
