I would have one, but Im not planning to sell my Suzuki Kettle to make space.
Keep them original - they still look stunning. Only downside (like everything in that era) is spindly forks and just about adequate brakes.
BTW I had a Griffin helmet & absolutely HATED. It was THE most noisy bucket I ever put on my head and probably a good part of why I'm deaf these days. I put up with it because it cost a lot and I was broke. The best hat I had at the time was a Cromwell full face - very quiet, but they stopped making them.
