Got the first bike today from a buddy clearing a lot I think it's supposed to have a tank. It's a derby. Cool kinda loop frame rear. Chainguard seems wrong. Anyone know the year? The other is spray painted over badge that's just square and nothing on it. My buddy pulled it out of a scrap dumpster for me.I put the wheels and bars on it just because I had them. Also wondering the manufacturer and estimated year. Maybe possible values I'm into both of them for exactly zero dollars so I think I did ok.
