Vespa 125 cc from 1951

This Service station manual for Vespa 125 cc, the "Roman Vacanzes", is from 1951. It was given to me by it's original owner who had just such a Vespa, bought as new. Long gone by now...
The manual is very extensive, approximately 150 pages. All in English (sometimes in Italian!) but printed in Florence (Firenze).
The Operation an maintenance is marked "5th edition. Dec 8 1951". Among the Accessories is a plexiglass windscreen mentioned.
