For Sale: Bianchi Sloping Frame Fixed Gear Bike

can someone who is well versed in bike converting and tube replacing answer my previous post and possibly look on gumtree where the same chap is selling his bianchi and there is a detail of the head tube lug and there is leaf shaped cutout on it??? isnt that bianchi trademark ???

what if thats a different frame altogether than jon the ex-webwanker is talking about??? what then???

Think bianchi used to put a big fat B in their lugs, leaf sounds more colnago

anything like this ?
