Hi peugeot mongrel and cyclotoine, many thanks for your comments. I do not intend to repaint the frame but had wondered whether there was any way to establish whether pink was the original colour. I haven't seen others so was unsure, but will not change regardless. There is also a longish scratch through to bare metal on one fork as a result of carelessness in a bike shop. I was going to try and get this blended over a bit (and thought paint codes could help) but perhaps even the marks without a heroic story are best left as is.
I don't know much history of it, I was told it was owned by an old Italian gentleman who had many bikes but that's about it, it came with decaying old tubs and looked like it hadn't been ridden for quite some time but the components were all in good condition. I don't think Galmozzi is known in the UK.
I have only seen one other bike with the two slots rather than the petal holes in the bottom bracket:

I have not seen brake guides below the top tube either, probably you are right it is 80s but I don't know, I await any clarification
I joined this forum to learn a bit more, even in Italy I have been told a few conflicting things, one guy swore it was a 60s de rosa
All the best and thank you both
