I just picked up a Columbia superb girls bike at a local auction last night, i believe its a 50's one. I dont know anything about bikes that much so maybe you guys/girls can help me. Where do you find the serial number. The bike is in rough shape, so is it a good idea to restore it. I mean sanding it down and what not(not the paint, just the crome parts because their rusty. Also what would the value be in its current state.
Non Tribuo Anus Rodentum and off to the next adventure (RIP)
From the low-res pic you provided, the bike doesn't look that bad. I'd start with a good bath. Some copper wool & WD40 followed with chrome polish on the bright work and some cleaner/polish on the paint followed with a waxing. You'd be surprised how good that will come up. The tires will probably come clean with a good scrubbing, maybe some Bleech-White on the sidewalls.
Remember, your bike is ~50 years old. It deserves to look like it was loved. Anyone cvan go to x*mart and buy a shiny new bike.
Serial number is probably either on the rear dropout or under the bottom bracket.
Your bike, right now is worth $35 dollars. Depending on who you talk to, tomorrow it might be worth more or it might be worth less. That's how this works.
Case in point; This past summer I bought a bike for $20, brought it home, gave it a bath, lube and adjustment.... Three days later I sold it for $150. Yes the initial transaction was undervalued, but the seller was motivated. The second transaction was a more accurate price, I maybe could have held out for more money. But bikes in the shed don't pay the bills, money does.
