From that oh so accurate source, wikipedia
KD 353 is now undergoing restoration at the Irish National Transport Museum in Howth, Co. Dublin, where KD59 also resides as a spares vehicle.
KD 70 was housed at the now defunct Glasgow Bus Museum but is since understood to have been scrapped.
KD 221 is so far the only member of its class to be fully restored.
KD 184 is in derelict condition at Kells Transport Museum in Cork.
KDs 156, 199, 236 and 241 are in private ownership
Would love another spin on one myself. Miss them, KCs, Ds and RHs.
