Look at this hot chick

[Salty]

Now that I have your attention.....I need some help.

I'm refinishing a cedar chest that belonged to my wife's grandmother that is almost 100 years old. I'm not sure if the trim is brass or copper. You can see the bands and their placement in the attached pics. While removing the bands, I broke several of the tacks that held it in place.

Question:

Is anybody aware of a website where I can replace these tacks? Also, can you tell from the pics if this trim is copper or brass? What is a good cleaner to bring the bands back to their initial finish?

Thanks for any help.
