Someone had mentioned that 144bcd cranks (Strada) had come into use by 1971.  My understanding is that the 144bcd Strada cranksets came into use much earlier, in about 1968, with the introduction of the Nuovo Record group.  They were not date coded until 1971 or so.

I have the same, but more difficult question with my own, recently acquired strada Pogliaghi.  It is number 9187, which I think puts it in the 1967/68 ish period.  A prior owner had fitted period-conistent parts including a 144bcd crank (Pat. no date code), Pat. no date Nuovo Record rear derailleur, old Record front derailleur with cable stop, and Universal 68 side pulls.  I think this would be perfect for a '68/'69 built bike, but am wondering if the frameset actually dates a tad earlier.  Also, curiously, this frameset does not have the hallmark diamonds cut into the lugs, but does have  "PSM" in the seat tube and all other lugwork, fork crown, and workmanship of Pogliaghi of this period, also original paint and decals.

I have a 151bcd crank and old Record rear derailleur that I could fit.  Calling out to the Pogliaghi cognoscenti - what should I do?
