Picked this one up yesterday. A friend of my dad's told me last week he had a bike for me and couldn't remember the name. Drove me crazy til I got it yesterday. Its a running bike, just needs new tubes. From a few searches i narrowed it down the mid 70's, not 100% certain though. Anyone got the inside scoop on decoding the serial? Imma bring this one back to life for my dad's daily rider.
