These keys are in very good shape. They were removed from a KS-32 but also fit the KT-76 and ASR-88 and some ZR-76 keyboards They also fit the Kurzweil PC88 and several other Kurzweil models. The picture just shows a sample key but you can just select the key you need. . Also note that some ZR-board used a different key with only one prong protruding from the bottom. We have those here. Please be aware that we can not guarantee an exact color match with your existing keys.
