Jan, this is probably a good question for you but I thought others might be interested in the answer so I'm posting to the CR list - and hey, its not another Masi thread (not that there's anything wrong with that)...
Were the French randonneur technical trials only open to French bike companies ? Did any other countries take part ? I know there wasn't a big randonneur following in Italy (for instance) but I wonder if some of the companies there might've still tried their hand in the trials, or maybe more likely, the English or Americans.
Also, Jan, with your contact with Ernst Csuka do you know if Alex Singer has preserved any of their old trials bikes ? Do they have some gathering dust in a back room, forgotten ?
