The significant measurement for the "seatpost" (the component with the saddle rail clamp, not the seat tube on the frame) is its diameter (27.2mm?.....26.4mm??...etc..). I think you are mistakenly measuring the seat tube length....
68mm BB shell width means it's more likely not to be an Italian made frame, as they usually have 70mm width BB shells....
