Another thing for the OP to check: it possible that the nice Miche 27.0 seatpost is not the correct size, the clue being if the gap in the rear of the seal lug shows signs of pinching.
It wouldn't be much but possible that a 27.2 is actually the correct size IF the seatlug and seattube were properly round and smooth in the top 6" or so.
Very possible that all the frame bits are "Italian" (and maybe all GPM) but I don't know of too many Italian made frames ffom this (mid-late) 1980's era that used that modified "Dutch-style pinch bolt" on the back of the seatlug instead of a lug with conventional "ears"...plus if it's really Brit BB threading then all bets are (farther) off.
The stay caps/tips I was try to recall may have been the ones used on some Gios, but they had a more pronounced concave "scoop" to them, so that's no clue. However there were some Bianchis that MIGHT have used a cap that's more like the shape of the OP's and those that I can find in my crude image search seem to be about the same vintage BUT these have the typical "B" in a circle panto...not much help
Definitely good point about the saddle post. I hadn’t noticed the pinch before. I’ll check it out when I get home. I didn’t have a chance to get it on the stand today as intended but thems the breaks. We’re going into an extended holiday weekend here in Denmark. The next business day is Tuesday so lots to do
I agree in regards to a mysterious treasure hunt like this. I’m usually pretty good at doing a deep dive to find info, but I think cycling in particular is one of those life-long passions where everyone has something to contribute. I love hearing from the old timers (I’m nearly 50 myself). I love hearing different perspectives about things that I at one time though I knew so much about.
Thanks to everyone for their input so far! I hope someone comes along with some definitive answer, but the journey is just as fun as the destination on this one
