Re:
I remember an Ijsboerke(sic.. :? ) Colnago team from the late '70s- yellow and green jerseys iirc. Maybe they were on different bikes the year before/after?
When you say: "one set of bosses" you are talking about bottle cage bosses, yes? not gear lever bosses...? Your frame would seem to fit in pretty well with the timeline. I assume there are no brazed on brake cable tunnels on the top tube, (or other later-in-the-timeline braze ons.)
You didn't say whether your frame has long, or short dropouts, which, (to the best of my knowledge) could be the clincher in dating it as being a new season's frame either one side or the other of 1977(ish.)
Thanks.. this is the kind of input that un-vagues us! If we can find a year in which both the old and the new are in evidence, it is a fair bet that we have found a usable 'not before' year. Maybe '1978' is that year for allen key brakes?
