A bit of help from vintage fans/experts needed here...
I bought the bike (ST56CC) pictured in the following photo album (click here) in 1988 when I was a teen and used it for ~2 years before moving progressively to larger frames (now ST61CC). The frame was not so nicely resprayed and Rossin decals were stuck straight on the topcoat. I then cared about the weight (9.8kg all equipped, not bad at that time), the great components and the ride (just superb) and so made a deal.
Being too small for me, I now hesitate between keeping the bike for the growing kids and putting it on the market. Either way, I wish to find out more about the pedigree of this bike so I can put it right. At the time I bought the bike, I had spotted identical lugs and BB shape/geometry on Olmo frames (Competition model, Columbus tubeset) - the Olmo-pantographed components also push in that direction.
Additional info:
Components: OLN 126mm, Campy SR rear derailleur (Brev. 1981) + front derailleur + Olmo-pantographed crank arms 170mm (1977) + Olmo-pantographed cogs (52/42) + headset, Sachs Maillard 700 Compact freewheel 13/21 BSA 83, 1.375x24TPI, Shimano BB 1.37x24T <52> EF, 3ttt drop bars + stem, Saccon Altex brakeset, Gipiemme seat post 26.4mm, Bio seat
Tubeset: there is no helicoid in the seat/down tube towards the BB suggesting SLX (I am not certain Olmo ever used SLX on a size 56 anyway); the 26.4mm is quite an odd one and may provide a good indication on the tubeset
Branding: there is nothing engraved in the seat stays towards the junction with the seat tube or on the BB - in the 80s, most Italian brands started manufacturing low/medium range models in Asia with engraving performed when reaching Europe; it could also have been filled up with epoxy, which I will confirm as soon as I take the frame for a paint job
Further details commented with the photographs
Any help much appreciated!
