I recently had my Shay on my desk just looking at something and after I took it back I found a small all bearing sitting on my desk. I have no idea where it came from and would find it hard to believe it was there before. It is smaller than a BB and silver. Has some residual oil/grease as it sticks to my tweezers. Can anyone tell me if that could have possible come from the Shay and where to look. Thanks in advance.
