Vintage cavity plate screws

[Cameron Lovelace]

After hunting for years, I have finally tracked down tremolo cover plate for my F-100. In getting screws for it, I'm presented with a few options: stainless steel, nickel, aged nickel, chrome. I know that I am really getting into seriously rediculous minutia here, but since I'm at it, does anybody know what the proper screws would be? Unfortunately, I can't ascertain from the controls plate screws. Thanks!
