You will NOT get your investment out of that bike, sorry to tell you. Around here, powder coating a bike frame and forks runs $100. If you want to make it look like a Racer, which it likely was originally, you will need painted fenders that color match with white pinstripes. Then there’s the decals, which are not available for ‘56-‘58 Racers. Women’s frame bikes just don’t bring much money. I have bought all the ones I have for $20 - $100. They are just far less collectible than men’s frame bikes. Even still, if that bike were a men’s frame, you still would not get your investment out of it after a restoration. That’s just the reality of the market.
I thought maybe you had some attachment to the bike, which is why you were interested in putting so much effort into a woman’s frame bike in that condition. If you are looking to restore and sell, you are wasting your time and money, in my opinion.
