Hey guys! I'm new here and was hoping you could help me out by telling me a little more about my bicycle. I pulled it from a deceased relative's cellar some time back, cleaned it up a bit and have been riding it casually for a few years now. Recently I've gotten more and more curious as to it's history, but my internet research has turned up flat.

Here is what I do know:

It is an Otasco (Ohio Tire and Safety Company) Flying-0 10-Speed "Ultra." The entire bike, from tire treads, to seat, to handle bar pads, are blue. I've replaced the tire treads due to dry rot (which really hurt me to do) and taped over the crumbling handle bar pads. The serial # is: HC1683243

Out of pure curiousity on my part, does anyone have any more information as to the history of these bikes? Perhaps estimated year of production? Where they were sold? How to read the serial #? etc ...

Any help would most appreciated! Thanks!

Nick
