There is a press photo showing a chrome lid. Don't know if it means anything since the text on it is talking about the bases.



Cool old pics there but press release photos mean nothing in terms of what production vehicles left the line with. In fact MANY press release photos from the day (from all makes) depicted prototypes of parts and cars that varied allot from actual production line vehicles. The same goes for some of those NOS air filter element photos, NOS over the counter replacement parts often varied from what left the production line on the cars. FWIW the cars used as references in those photos are some of the best restored MW cars on the planet, I've seen them all in person. But as good as they are, they are not 100% exact, for instance, none of them have correct fuel filters (all originals were plastic, not metal).
