Unfortunately the images on that set are cropped too much. As Otis mentions, the later bikes were different. I have seen one example with the legwork similar to yours, but it had original paint, the lugs looked more carefully filed and it had the head tube stamp I mentioned, those lugs were pretty common actually. That head tube stamp is three lines, GALMOZZI in the middle and some additional type set in complimentary arcs above and below.
