I'm sure someone was looking for one of these. Well, today I found one as I was doing a new year's tidy up. I no longer have a Pantah (haven't for about 20 years...) but I still have a complete workshop manual for it - not the owners manual which I never got with my second hand bike. I am happy to send this to whoever wants it for the cost of the postage (from Switzerland unfortunately). If no one shouts in a week or so, it will be sent to recycling. First come, first served. I should point out one thing: it's in Italian. But hey, how hard is Italian to understand? Google translate is your friend. And there are loads of photos of stuff in it.
Don't throw it away. If no-one else wants it I'll have it - although I already have it in English. The Italian versions are picturesque and more entertaining. I might pass it on to someone else if they need it.
Took a look at my Pantah manual, and it is in both English and Italian. The translation is a bit loose - there are whole sentences in Italian omitted from the English version, in places.
