[QUOTE=SachaV]I have a 1979 Miele racing bike and it has a full shimano set but i don't know what model it is. The crankset and brake levers look alot like '78 dura ace ex but they dont say dura ace on them, they say shimano and have some sort of bow and arrow logo on them.

This is what is called the 'arabesque' style; so it's either first generation 105 (ca. 1982?) or 600.

If they look the same as these, they're 105.
