The frame is Huffy, the rest is a hodge-podge of parts. Huffy made it easy to decode their serial numbers, The first number is the last digit in the year- 5H********** would be a '55,'65, or '75. You would have to go to old ad pics and compare frame details to determine the decade.
Yeah looks my 1970's Huffy Daisy. Waiting for my 7 year girl to get tall enough to reach the pedals. Otherwise I look like a real loser riding alone on pink tandem. $20 is a steal!
looks like a huffy daisy daisy with the correct bars. probably worth the jackson, but they're a pain to have in your garage. good luck with the new project.
