B/3 Bosch Dynamo cover

Does anyone know of a supplier for the end cover of a b/3 dynamo end cover - the cap that goes over the voltage regulator on R5 and R51 models?
I've tried all the usual German suppliers but they say this glorified tin can is unobtainium on its own and can only be bought as part of a new repro dynamo!
Thanks in advance.

They come up on eBay every so

They come up on eBay every so often.

I believe for the twincam bikes, that you need the version of the cover with the bottom edge rounded out to fit the motor casting. That's my/our suspicion, anyhow...

Yep - that's the one. I've been looking on German Ebay for about a year now but nothing (usable)so far.
Thanks

Yes. Thanks for that
but I think I'm sorted now through a different forum. If it comes to nothing I'll be in touch.
