[Bellerophon]

This came up a while ago when a member from Switzerland wanted to know what
colour to paint his block. All the blocks left the works the same colour,
this was a universal one used by many manufactures at the time, and I told
him that Sulzer in Switzerland used it for one and to see if he could
obtain some.
There are some dealers offering engine paints, of course it is not easy to
match as they have names such as (duck egg) but they usually have a spot of
colour on the tin. So, if you can find a photo or a car with the original
colour a green/grey you should be able to find some at a good dealers.
Best of luck,
Bellerophon
