I'm guessing you've either got the model above the ones I remember seeing, or there was some varience in bikes made back at that time.

My memory of Chiorda's from Erie in the early 70's was a basic bike selling at the local catalog stores for about $79.00. The frame was very close to yours except that the lugs were painted black, identical crankset, and the derailleurs were Campy Valentino. Cheap, but far and away the best quality bike you could buy out of a big box store back then. Not seen too often. And considering that an absolute garbage Iverson sold for $69.00, and a Raleigh Record went for $100.00, they were a pretty good bargain.

I've always had a bit of a fascination with them, although I've never been quite sure why.
