It does, a Campag type on top of the stay, and strangley further from the drop out than all the Benottos I can see?The decals look like ones used on Benotto 5000 in the mid 80s. So possibly repainted?
Does it have braze-on RD cable stop?
Can you meassure the seat tube ID?

I'll have to check again, but it's over 2mm at the top!!!
The BB shell has absolutley no markings, just two ovalised cut outs. Posting an image of another frame, but exactly the same as mine.
