So the t-masts were simply painted silver?
1401 bright silver is a metallic paint, are you saying this is close to original paint or are you trying to mimic some sort of plating?

The finish on mine was pretty dull but condition and age make it tough to say if it would have ever carried a shine or not. Considering I had no reaction in acid, it's safe to say no zinc coating was present.

Just trying to be sure on this prior to refinishing
