Help me to identify a giant bike

[Csehmarton]

Hello!
Are there great experts who can help me identify a giant, 65 cm tall beatiful roadbike probably from late eighties?
The bike is has just been discovered, I suppose it hasnt been much modified.

What I already know:
material is reynolds 531
campagnolo dropouts
the spoke heads have clover marks
on velobase I didnt find head tube badge with such shield shape
it is equipped with 6207 or 6208 shimano 600 set
I cant yet tell if the bb shell is italian threaded or not
I emailed that bike shop in Munich, of which there is a label on the bike, no response.

Many thanks for any help!

Re:

I did days of research on internet, but I can't identify the bike.
All remaining stickers and paintwork (probably the groupset as well)  look original.  It has the trace of a Saronni sticker on the headtube.
(https://lfgss.microco.sm/api/v1/files/3 ... a6d13d.jpg), but otherwise has nothing to relate to Colnago made Saronni, no engravings, different lugs. My idea was it might be a late "Tecnocrat" Saronni (without engraving) but Tecnotrat Saronnis have different lugs and dropouts, even different badge.
The paintwork and lugs look much like an Oscar Simonato (e.g. https://www.velovilles.com/en/parts/fra ... -oxid.html) but other details are different, no 'S' engraving, cable guide is under the BB shell, in general it looks younger (mid-eighties imho). Oscar Simonato bikes have no serial numbers or are made up from 3 or 4 digits.
In general it looks a nice Italian bike (BB shell is 70 mm wide), but oddly it has a Reynolds 531 sticker. Dropouts are clear BREV. CAMPAGNOLO. I emailed the bike shop in Münich (Fahrrad Reisenhuber) where the bike was sold once probably, they gave the Saronni hint, but could not tell for sure. Any tips are very welcome!
