So I picked up the Dawes Galaxy. It looks to be an early-mid 70s model. It was cheap, it was nearby, and it's classic British. Perfect bike to tinker on with low expectations.
Overall in good shape, though the paint is tatty. It could be rideable as is without too much work. But if I can find better quality period replacements cheap - the derailleur is pretty sketchy, the stem mounted shifters are hokey, and the suicide levers have to go.
In my grandest dreams I would outfit the bike with full fenders as some of them were supplied. We'll see how far I get though.
