Schaller Guitar Rock Pins Chrome, with guitar-side receivers These are genuine Schaller rock pins, highly valuable now with the "made in W Germany" (former West Germany) stamp from before the reunification of Germany. The condition is good with little clouding and no noticeable scratches, so I haven't used them, keeping them as a collection, but I'm offering them for sale now. Although they are in beautiful condition, they are old products, so there are some minor scratches and slight clouding due to aging. Please check the photos.
