I am not trying to sound like a complete a$$, but I would look for a different frame to build up. That BB is completely destroyed, and I would question the alignment of the rear stays after seeing the pictures. There are so many nice frames on here and other forums that would be a great starting point. I am not sure you will ever know who the builder was, but this we know for sure, this is not a Galmozzi. If you are seriously interested in a nice Galmo, I am positive you can find one at an affordable price given the market right now. Good luck with your search on this frame and future ones.
