The cross-shaped cutouts sound unusual. I think they will be the key to identifying the frame manufacturer. As you said, it is an Italian frame so that will narrow the field down. I have confidence that someone will be able to identify the builder. Most cutouts I have seen have a fairly distinctive heart shape that seems to follow the outside shape of the lug - a cross-shaped cutout is distinctive.
I think the frame purchase price is quite reasonable especially with the Campy. components.
