So, this bike is branded Highlander. Nobody mentioned the origins yet. What I find interesting is that I know that a bunch of Highlander branded bikes are flooding the Danish market, or at least were years ago. Dating back to about the 80s, they seemed to do imported far east asian framesets and then eventually went down the alu commuter route that all the rest of the Danish brands did. This is definitely not a Highlander like the ones I know from here. This is far fancier and very, very pretty. I'd be really interested to know where it's made and when.
I haven't checked yet the the bottom bracket. Indeed for the bar and the seatpost is Campagnolo.There had been some Japanese Highlander Bikes, from Takara, Mid to End of the 80ies.

This one is obviously looking much better , alone by the style and paint job but also used ITM bar, i would say this is Italian
@Jc24 Have you checked the Bottom bracket already, is this ITA standard?
Therefore I would say a Brooks is no option at all, but the saddle has to be Italian too.
To me, BTW the "unknown bike of the year", it looks so lovely.
No serial number foundThis is lovely.
If it's a frame from somewhere in Asia and there's a frame number you could compare to those here: "Asian Serial Number Guide - Bike Forums" https://www.bikeforums.net/classic-vintage/1042901-asian-serial-number-guide.html
Might provide a clue.
