New to this site so if this isn't the right forum go easy on me. Recently bought a early 70s World Finest Bicycle by Sekine. I'd never heard of Sekine before this purchase but fo $40 it looked like an interesting project. Brooks saddle, dia comp and sun tour components etc. Question is about a Sun Tour "Quick Pattern" clamp that was on the stem above the upper bearing cup and below two spacers and the brake cable guide. Looks like a quick release seat post clamp but I found it on the stem. Was this originally supposed to be on the stem or was someone before me using it as a spacer? If supposed to be on the stem, what's its purpose?
