I wondering if anybody might have a diagram/drawing of a petrol cap assembly 1940/41, when I got mine back from the paintshop it does not appear to be assembled correctly. I have looked on the web and cannot find anything.

Hi Derek,

That is how it looks like from the bottom.

Not too many ways to achieve that... (-:

Cheers,
Noam.

Yes I have seen that picture perhaps my petrol cap is missing something as it no longer fits together as the picture shows hence why I need an exploded diagram to work out whats wrong.
