I have a slightly used 10" serrated contact wheel and bearings for a Bader III grinder. I ground about 20 blades on it. I has a small cut less than an 1/8" of an inch deep in the middle of the wheel on about 3 of the serrations on the wheel. This small cut does not influence the performance at all. Other than that, it is in great shape. $275 plus shipping. Paypal or US Postal money orders accepted.
