Water pipe finish?

[1939mars]

I found a great site with finishes under the hood at:
https://model-a-ford.org/top-page-1...ormation-indexes/finishes/engine-compartment/

But, I can't find the finish for the water pipe on the side of the engine between the two hoses, or the petcock in it. Anyone out there know what they should be?

Thanks,
Scott

The water inlet pipe is gloss black and the valve is bare bronze as cast.
