It's a Centurion. Generally good bikes. Frequently copies of the Italian bikes of the era, those were good bikes to copy. The Accordo is toward the lower end of the range, so while it has pretty much the same geometry as the high-end, the tubing is a little more bullet proof against dents and the like. Excellent find for the price, and will make a nice fixie.

[Edit] Nice red paint. And Centurions are known for tough paint jobs, unlike my chip-at-a-glance DeBernardi trackie. I'll guess late 70's, very early 80's based on the solid paint. If you post the serial number, someone will give you the exact year.
