[link] the bridge was metallic silver from stem to stern. Now I don;t know what planet the good people at Model Power inhabit but down here in South Carolina most of the surviving signal bridges of this design are painted black with concrete bases.
To start off, I painted the bases Testor's "Flat Light Aircraft Gray," which makes a nice concrete color. The I painted the rest of the structure black and then weather washed the bases. I finished off with a coat of Testors Dullcote.
