I bought the MB 1 off Craigslist 2 or 3 years ago. The bike looked showroom when I bought it. When I opened it up to overhaul the bike, the grease was fresh (or as fresh as 25 plus year old grease can be). The bike had never been ridden.
The 1969 Robin Hood was also pretty much showroom. The saddle was missing but the bike still had the original Dunlop tires with the nubbies on it.
