Thanks Dan for taking time to reply with the idea.

Oddly, the bottom bracket has no markings at all. I searched the rest of the frame in case it's perhaps somewhere else. So far no luck. Not even a serial number. It's starting to look like a department store bike.

I'd forgotten about the tremendous amount of data matching information on Sheldon Brown's site. That's a great place to explore & learn (and spend a whole lot of time).

Thanks Again & Please Enjoy Today!
Paul
