Vintage Grover tuners. $100.
These are vintage mid-century tuners with a high gear ratio, such as were found on the Harmony Batwing and other mandolins from the 1960s. If you happen to be restoring such an instrument and want some period-correct hardware, these could be just what you need. In good shape, working well, no missing teeth, etc. Tuners only, no bushings or screws. See more photos, call 425/772-0231, or for more information. $100 plus shipping.
