Ah my typo! I found only one other Mattolini on line: http://www.eroica-ciclismo.it/schede_bi ... inotti.pdf
Thank you, I have some brown gum campy hoods sourced so that's not a problem, also available is either a Rolls saddle or a Iscaselle Giro d'Italia in perfect condition ( same as: http://bianchista.blogspot.co.uk/2011/0 ... addle.html
There are more detailed pictures here: http://www.flickr.com/photos/51987088@N ... 1220012856
The fork inner lug work and dot cut-outs on the lugs and fork crown look like early Colnago.
Thanks for linking to the detailed photos. It is indeed an interesting bike. My suggestion that it might have been produced in the same place as Colnago bikes seems less likely after having seen the detailed photos. There are simply too many inconsistencies and the finish work is not quite as refined as what you would have found on a Colnago at that time. The fork crown, the lug shorelines and the rear dropouts do not show the same dexterity and/or time spent with the file.
From the components and frame details, I think that you can say with a reasonable degree of certainty that the bike was produced between 1973 and 1976. The stem is post 1972, the rear derailleur is marked 1973, the cranks are marked 1973. The frame still has cable clamps on the top tube (generally meaning pre-76) but braze-on bottle bosses (generally meaning post 1972).
Did you do the partial repaint yourself? If you did, I must complement your work. I did not notice any blending and the orange peel is virtually non existent.
As far as a saddle goes, the Rolls dates from the 80's (see on my Marastoni here above) and the Giro d'Italia from the 90's (I have three of them on my triplet), so not quite in keeping with the vintage of the bike but still more in keeping with the drillium.
