I've been doing a bit of research into unrestored bikes. There's no doubt it is the way some see things going, at least in terms of what is at a premium for sale. For me, this Comet is a great time-piece: how Comets looked before prices of them really took off, and from a time when Vincent owners might run one during the winter maybe, but leave a twin in the garage till spring had sprung. So, as such a time-piece, I voted to not restore. Clean it, ride it, leave outside the pub half an hour longer than you would a twin before checking it's still there. Such use is a part of this model's history. Nice to have a few around that reflect that.
