Being an EM pin collector and doing repairs on my own pins and some that I intend to sell. What are some used parts I should buy to have on hand? I work on all brands so are there known items that go bad on certain brands that I should keep extra of? For example I have a couple of extra score reel boards for Chicago Coin machines because they burn the traces. With all the vast knowledge here I figure we can create a list.

Yes I do have Majorettes. Awesome pin. I’m aware of all the usual repair parts that should be new. Rings skirts etc. I’m talking used only parts that may be hard to find when needed.
