Hi Vincent,
OK, Since I wasn't present at the end of the production line when every pagoda was produced, I can of course not be 100% certain that what I believe to be the case is true. It's just that you sometimes get a little tired of hearing people making claims that stuff is original when you strongly believe it to be incorrect information.
Then again there are some genuine factory modifications that I've seen on MB cars from that era, but that would then normally be documented on the production/data card for that specific car as a special production order of some kind. For the W100 this was rather common,
on the pagodas I doubt that they where there where many special orders like that, but they do probably exist.
As I'm sure you know, the markings of the hood, Soft-top cover, Hardtops etc. was an essential aid in the production process to make sure that the correct, custom fitted panels/items, ended up on the matching again car after being prepared/painted separately. Early cars and late cars had these markings, and I see no way why they would skip that crucial part of the process for one or more cars. It just does not make sense.
If the black paint on your car is original, then one would assume there is a note for that in the data-card. If you could provide the data-card
showing these modifications documented, that would of course be of great interest.
From your description it appears that the engine compartment had the silver paint and clear coat paint applied before it was painted black.
If this was a special order, why would they first paint it silver before painting it black?
The only reason I think it's worth discussing this, is to ensure that if someone is looking for info on how these cars are made and what is original and what is not, they should be able to trust the WIKI information found on this site.
Best regards
Hans
