The other 46 wheels in this lot look exactly like these four.They are quality wheels with many plys and all are unused - probably for use in a portable grinder/ polisher. Thanks for looking - I have  2 lots of these listed - if you are interested in both, I will save you some money and shipping will be less. Thanks for lookin - if you have a few moments, I have other tools listed, both antique and contemporary. (LS1 - 1218)
