Sounds like you're making good progress on your A. Pictures would be great. Just a note on stock colors for a '30 Model A:
- chassis were all over semi gloss black.
- fenders, splash shields, and running boards were dipped in a gloss black.
- all body components, cab, bed etc. were "sprayed" body color Inside and out before being mounted to the chassis. As a commercial vehicle the paint wasn't buffed out except by special order, so would be semigloss. Most restorers do a gloss finish which is actually easier to do today.
- that included the wooden slats and tie strips on the bed. Many restorers Do a natural finish on the bed wood because it looks nice, but they never came that way from the factory. Other exposed wood, like the beam's the bed rests on, would be a dull black wood preservative.
- interior metal was sprayed at the same time as the rest of the body, and hence body color. The trim cardboards on the doors, kick panels, thin strips around the door frame, and the seat were a black artificial leather in 30/31, brown in 28/29.
- front bumper was "Rustless steel", Ford's term for stainless. No rear bumper. Same finish on the instrument panel, door handles, window cranks, and latches.
Colors for the Model A are incredibly well documented for a car only built for 4 years. The national club's judging standards are close to 600 pages long. Google the Model A Ford Club of America (MAFCA) and the Model A Restorers Club (MARC) for lots of photos and info.
