Got this from the original owner.She got this for her 7th Christmas in 1949.Was purchased here in Kansas City at the Sears store.She said she was balance challenged and this was a gift from her Father.I guess Chain Bike had a history with Sears?Also werent they a parent company for Ross?I got it for my girlfriend because she fell in love with it.20" front tire and 16" rears.Skiptooth chain needs oiled but it still rides smooth.I can see it gettin a little rehab..not too much though.
