Pinarello ___?

I picked this up a few weeks ago. It's pretty much mint - everything is on top condition, hardly a mark on it, a few small chips in the paint and the decals have been replaced but other than that it's almost as new. Groupset is a mix of campag record (gear levers and front mech) and Zeus supercronos (rear mech, chainset, hubs, brakes). The brake levers are a later addition (I've seen this many times - later aero-style levers on earlier bikes) but actually fit in quite well. The previous owner has sanded them down to remove the logos and make them fit in slightly better. It came with mint shimano 6400 clipless pedals too (not shown in these pics). Tyres are modern too. Chain is a very unsed sedis.
There's only one problem with it - it's too small for me It's a 54, and I need a 58/59. So once I can work out what model frame it is, the frame and fork will be up for sale so that I can find something my size to hang the parts off!

Any help identifying the frame would be appreciated - it's definitely a pinarello, but the model name is missing. Paint is original as far as I can tell. Headset is english threaded, BB is italian. Seatpost is 27.2mm. Frame number is B862.

now for some pics:

Can't help with the ID but that's lovely!

Re:

Nice bike in my favourite Pinarello colour. Shame it's too small for me to.
Frame and forks should make £300 - £400.
It took me about 3 yrs to find a good frame in my size so if you see one in the right size don't um and arr about the price just buy it.
Here's a link to what looks to be your frame.

Thanks, that link is useful - it certainly looks the same

while replacing this one with the same model in my size would be ideal, I could quite happily go for something else from the same period - I've always fancied a merckx, amongst other things

it could be a pinarello montello?
i've sold one month ago a stunning pinarello replica... but it had the internal routing for the rear brakes and another tipe of lugs for the node between horizontal, vertical and rear diagonal tubes...

...wait wait wait..
thanks to CicleExif I've just discovered that Pinarello had also in its catalogue a model called "Record"...

here some details... could be the same model?

The link posted above was to the Record. From what I've read, the record was the predecessor to the montello. Will check out cycleexif later

Thanks

Re:

Nice, looks like a Treviso. 27.2 would fit with it being SL which matches the quality in bothering to chrome the forks and stays. It's not a Montello as they tend to have internal rear brake cable routing and no chainstay bridge.

I don't think it's a treviso, as those didn't have the chromed seatstay caps (none of the ones I've seen, anyway).
The closest I've come so far is the Super Record Special in a link posted above. I'm not sure which features (if any) were swapped or handed down between the various pinarello models though. I haven't been able to find a complete catalogue for each year, so it's hard to determine exactly what year and model it is most likely to be.
