A 26.8mm post would be correct for an Aelle seat tube . Based on the presence of what appears to be Columbus dropouts, the decal styles and a G. Olmo fork crown, I'm inclined to place this circa 1986-1987. The paint fading around the circumference of the tubes, as opposed to the more traditional along the tube length, is intentional. This style was by some Italian brands such as Olmo and Ciocc around this time. We've seen other Olmo with this style of fade, in other colour combinations (see attached pic). Enjoy your new acquisition.
