B31 Alternator pictures please?

[Stebbing]

I have a 1957/58 B31 (alternator model). The alternator cap is missing and I cannot be sure if the ones I can find on the web are the right model.

Does anyone have a similar model? Would you mind taking a close-up picture for me? Also, is it secured with clips? If you could take a picture with the cap off, but the clips in place, that would be even better. Many thanks in advance...

hello, do you mean the distributor cap? they are very distinct from other types on the b31.
