I was working out in the woods today, and I found this in a metal pile. No bike unfortunately
The crank arm is 7" long, and the pedal spindle is still attached/fused to it. The bottom bracket is still attached as well, and it looks like an appropriate width for a bicycle. It has 30 teeth (including the rusted off one). The ring is 9.5" in diameter from tooth to tooth, compared with a 48 tooth Rudge which is 7.75" in diameter measured the same way.
Anyhow, enjoy the pictures
