Yes, I see now that he added that. 8) I thought it was a fruit. Thanks but I have been slow with the IDs lately and I dont have a clue here. Is it hollow?

Probably a ball from an old check-valve used in some type of pump. Most likely made of red brass. Tony

Here's the balls from check valves made out of a newer material. http://www.ceradyne.com/products/oilgas/ball-check-valve.aspx They come in all kinds of sizes. Very good possibility.

Re: un known ball

Most check balls and floats that I have seen are plastic. Could it be rusted plastic from the water?

Re: un known ball

Are you sure its copper? I would expect to see some green if corroded. The color of the camera may be off but it just doesnt look copper to me. Is it heavy? Is it solid or hollow?
