My Big chainring 12 speed Moulton has got stuck as i need a nice 80's / 90's Crank set. It needs to be 135 BCD not bothered if 170 or 175, square taper. Posted or can collect up to an hour from Oxford.
Was going with this Miche comp which is the exact look just the wrong BCD
I reckon cranks generally became smoother and rounder with the move to 135bcd. The look you want is more associated with 144bcd.
Planetx used to carry a retro look crankset in newer bcds at one time, maybe worth a look there
