I have a question concerning a couple of old bikes. My Mom has a couple of old Raleigh 3 speeds with enclosed chains and generator lights from the early 50's. I spent a lot of time as a teenager trail riding and otherwise general beating on Dads, and it didn't miss a beat. They have become a bit dilapidated from being in a damp basement, but look like there is potential. Are they worth restoring? Are they worth anything? I'm looking for a project. TIA.
