When we had Highway motorcycles in ferntree gully we got the RH from Melbourne motorcycles Peter Jones and Graham Lang in about 76 and sold it to Peter Simonds MCRCV i was going to keep it but had an RM250A so didn't see the need.Peter rode it a few times and I'm not sure what happened to it after that. the RN would have been sold to someone looking for a quick bike id say. My brother ran into Peter Jones both ex Sandringham members at the Island classic a couple of years ago and i think Peter would remember what happened to that bike, he is living in Tassy somewhere.
