color or 1934 Ford original Stromberg 48 Carb

[FrankWest107]

Just finished cleaning up an old Stromberg Carb and wonder what was the original color?

I have seen a lot unpainted? Was that original in 1934?

The zinc alloy castings would have been chromated (cold dip - greenish, goldish color).

 

The cast iron throttle body would have been rust brown after a few weeks, as it was left natural.

 

The steel linkage, screws, etc., would have been electroplated with zinc, either white, or white with the yellow conversion coat.

 

Some of the Strombergs used on the high end cars (Packard, Pierce, etc.) had different finishes. Example, the EE-3 used on the Packard 12 would have the castings painted gloss black after the chromate, and the steel linkages and screws would have been electroplated with dull nickel.

Great! You really know your stuff.

What can I coat with so that it does not rust...Just a lite oil coat??

There is a high temperature engine paint in a "cast" color. It is a tad glossy compared to iron, but unless someone leans over the fender and inspects with a glass, it is pretty close.
