Koga-Miyata Randonneur.
Bought as a battle-scarred frame set, rattle-canned and in use as a test bed for parts I find and want to give a try.
Version 1 sported Claris brifters (work well, but the jury is still out on the looks), an Andel compact crank set (nice René Herse clone), Tektro CR720 cantis (meh ...) and a cheap (€100) new wheel set from Taylor, including a hub generator (not too bad!):
Version 2 had Nitto randonneur bars and Campag brifters (comfy!), a Gipiemme triple (kinda cool), MAFAC Criterium brakes (fine) and Lyotard Berthet pedals (excellent):
I'm currently at version 3, with Athena 11-speed brifters (really nice, but not as pretty as the first generations of Ergos), TRP carbon MAFAC copies (a bit OTT, but they brake really well) and an Idéale 90 saddle (lovely):
