Are you certain that your PY10 is from 1980?
Doesn't the 1980 PY10 have a black plastic bottom bracket cable guide?
I have a 1979 PY10 with the cable guide above the bb and I have a 1980 PY10 that does have a black plastic bottom bracket cable guide. (See the photo's you posted earlier this...
I think it is very close to the PX18 of 1980.
Even the funny taillight!
Look for 1980 Catalog-UK on this site:

We had a stop for a few days at the Como lake and stayed in Montegonzi (Carviglia) at La Forra (agritourismo) in the Chianti region.
L’eroica is a permanent circuit of 205 km in the form of an 8.
Breathtaking scenery!
We participated at L’eroica last year.
My wife did the shortest distance: 38 km.
I had trained for the 135 km but that was to difficult and I did the 75 km distance.
Accommodation is widely available as it is the end of the touristic season.
If you intend to do the 135 or 205 km start early...
