Petrol tank cap/anorak question

[yellow B31]

My 1949 B31 has been rebuilt by a previous owner with much stainless steel being used to replace the original fixings and fastenings.
One item that looks lovely but is a rubbish fit is the s/s petrol tank cap so would like to replace with a good used original one.
Did BSA use a particular manufacturer/supplier or are they all much of a muchness?

Mine are Ceeandess (or some similar spelling for C&S)

Thanks. Something you don't think about until you see how rubbish pattern parts are.

Hi,

I bought 3 new petrol tank caps from C&D Autos and they are good quality and fit well.
