guerciotti's from this time period were highly variable in quality- tho generally the pre-78 bikes were very nicely finished, demand must have increased dramatically with ten speed drive distribution. some would be quite nicely crafted with finely thinned lugwork & crisp brazing and others showing indifferent build, file marks and overly heavy paint. ime, handling (at least on 53 cm c-t & smaller frames) was very quick -ie- more like a ciocc or cinelli than say a colnago or masi from the same time period
