What Pinarello did I buy?

So I bought this bike. It's metallic pink and it's a Pinarello. But there are no decals on it. Mostly Campy Record with a Sugino crankset. Both chainstays are chrome. The second set of bottle cage mounts on the seat tube may have been drilled and tapped later. So do you know model, year this is and what it may be made of? Thank you.

Made of steel.

Whatís the serial number?

Why do you think the second bottle cage holes are later additions?

Hope thatís not a crack near the seat binder bolt.

The bosses are different for the bottle mounts....there are none on the seat tube. Serial number looks as if it says " A16" and that's it. That's just the paint by the seatpost.

I agree about checking what that dark jagged line is at the base of the right seatlost clamp ear on the seat lug. I does look like it could be a crack.
it could also be just be the edge of the paint flaking off the clamp ear. It's good to be sure.....

Pretty sure they didn’t always use bosses. Simply drilled and tapped the tube.

True, I couldnít see properly on my phone. In that case itís probably a Treviso. Iím not convinced the paint is original as they didnít finish the paint off square like that on the chainstays.

Intersting serial number, doesnít fit in the common formats.

My Montello has bottle mount holes simply drilled and tapped sans boss, but they are both like that.

I'll cast my vote for a circa 1985-1987 Treviso frame in Columbus SL.

Thank you for that information. I'll have to take a better photo of the chainstay / bottom bracket area today.

Thatís how my Treviso was set up: bosses on the downtube, drilled and tapped seat tube.

The seat tubes aren't just drilled and tapped for the bottle mounting holes. A typical SL seat tube has only 0.6mm wall thickness in that area, while a typical boss bolt uses and M5 x 0.8 thread. Consequently, a perfectly tapped SL tube would only engage a bolt for 3/4 of one thread! Take a look inside one of those threaded holes and you'll find there is lot more material than 0.6mm. It appears to be a standard boss that has been ground/filed down to a flush fit.

Thank you for that info T-Mar. Here are some other photos of the bottom bracket area. The dropouts say Campagnolo.

Makes sense when you stop and think about it.

The seat lug looks fine. No cracks. The same color is inside the fork on the steering tube which leads me to think it is the original color, or it was an exact match.
