I dont know whats going on but lots of mid 70s Bianchis are popping up on Ebay. Seller says a Canadian expert pegs the bike as a 1975 based on the serial number. I think it may actually be a bit earlier based on the plain fork crown and raised ''Bianchi'' on stay caps.This is definitely a missing link bike in my mind.Campagnolo ends point it out as a Reparto Corsa built bike Later bikes had raised lines on crown then circle Bs. He does show the WC 72-73 decal from the side so we know its 1974 on
