Don't know if this is too late for you, it's an early 1990s NOS Miche double with original Miche 52/42 rings fitted, has the Campagnolo 135mm BCD. 170mm length. It can be a triple as it has a set of inner bolt holes (74mm BCD) It was mounted to an insurance replacment bike from the early 90s that I bought about 15 years ago that had 7x2 set up.
