I'd appreciate I.D. on these old clipless pedals. They are possibly early 1980's, and are simple in the extreme. The attachment surface is nothing more than a black cylinder, 4.5cm in length, 1.8cm in diameter. Total length of each pedal: 8.5cm. No markings of any kind. Spin smoothly; somewhat light & seem well-made. If you know them; I am looking to buy their cleats. They came from the garage of Alex Stetina.
