Button?

[oklhhyde]

Ounce this and I am not sure if it is a button or what exactly it is. Any help in an ID would be much appreciated.

Need some better photos to tell. Thanks

It is kind of hard to get very good pictures. The only detail I can really see is there is a hole on either side of the little know sticking out. It has a rounded knob on the front and a flat one on the back.

Any ideas for removing rust from it would help as well

Based on it's size and on your description, as well as what I can see in the photo, and.. (and this is a big AND).. if my memory serves me correctly, I am going to say that your item is not a button, but rather a part to the plunger of an OLD wheel (brake) cylinder. Here is a photo of a newer one (well not really new, but more recent than yours would be if indeed that is what it is):

Definitely so etching for me to check into. After looking at the one you posted it does seem to look a lot like mine. I will do a little research and see if maybe I can pinpoint the year of it. Thanks tons for the suggestion.
