Couldn't resist it (it's a desperate hobby, I know). Bought a Callegari Superalcione America. Was just lying there and whispering to be used again. Tubes holding air quite well, though they will probably need a latex inside treatment. I guess the Callegari is from around 1980, not sure. The beauty of this boat lies in the wooden structure that is built underneath the wooden bottom plates. Brass parts here and there, so some polishing to do. If anyone of you has some more info about Callegari in general or these boats... much appreciated!
