ok ive been looking for hours and cant seem to find anything. i have an old skip tooth and the badge on the front says chicago cycle co liberty. which i found out is a schwinn with a different name. so i started i looked it up in the schwinn vin database and it came back as a 55 or a 57 but that isnt old enough because of the story behind it. its my girlfriends great grandmas bike from when she was a girl her grandma was born in 47 and claims the bike is older then her. so it does NOT have a welded on kickstand so that means pre 46. but after that i get a little lost. the vin is on the BB and it is R50850 it has rear facing drop outs with bolts it has locking front forks. it does not have a chain guard on it. any help would be greatly appreciated. i know these or horrible cell phone pics but i can get better ones if need be. and if you need me to take a specific photo of something please let me know what
