    Description

    These come from the College of Wooster Physics Lab. They are antique brass balls on rod, very pointy at one end, be careful. These could be shined up very easily, but I will leave that to you. The would holder is nice. These were made by Riehle Bros. Testing Machine Co. of Philadelphia. Most of what they made were machines and college lab demonstrations on testing the tensile strength of metals and other materials. I don't know how or where, but these were used in one of their demonstrations. I'm NOT sure on this. If anyone knows what these are, please contact me. I cannot find them on any photo of Riehle items, and I have searched a lot.  Cleaned up they would make nice decorations! Be careful, the bottom tip is very sharp. Keep away from your eyes!
