What I've found are:
  - a galvanized plate--my guess is the back plate of an electrical outlet
    box that was never installed
  - brass shelf structures, no patina
  - shelf supports of probably aluminum or white metal.

My windows have non-specular metal louvers, but the surface finish is absolutely
non-metallic.

In places other than my home, I've seen railings, plumbing fittings, and
(possibly) door handles that fit the bill.
