I purchased this beautiful vintage bike from Facebook today to cruise around town. The previous owner said she believes it's from the 1960's but it's been painted at least twice and I cannot find any brand identifiers for the frame or breaks. There are two numbers stamped on the underside of the crank, 4629213 and 503.47312.0. It is a 10 speed with manual shifters below the handle bars on the headset. Any information would be appreciated!
