I'd say you are correct Jeff regarding the 144 BCD cranks being introduced around 67/68........also, forget now who noticed that track cranks don't seem to be dated, but I checked my 'Piste' crankset from 1975 and sure enough they are not dated.
I'm not a Pogliaghi expert by any means.......but I think which ever period you chose...67 or earlier it sounds like you will have a desirable bike.
Should you choose the 151 BCD and Record rear gear version I would think you would need to fit the front gear with the chromed bronze arms and non slotted cable stop [a generation 2 front gear] as opposed to the type with alloy arms and slotted cable stop [gen 3].....and perhaps Universal mod 51 brakes...or even mod 61s? for it to be period consistent.
