Picked up this rusty crusty wagon for $10 on Craigslist, it's in pretty rough shape, the bottom is rusted through, 3 of the hubcaps are missing, one of the support bars is disconnected because it's rusted through where it attaches, and the handle is bent up pretty bad. Any idea on manufacturer and era? Is it worth it to try to sell this, or just keep it as garden art? Thanks for any info you can give me!
