Thank you again, to all those kind and helpful Glocalers who responded to my request for information on a L, S or S Swiss driving licence. Guess what? I found it six months later!!

It was in a small zip pocket of a rarely used bag which I took as a 'carry-on' flight travel bag instead of the usual wheelie.

Just to let yawll know, and to say a big thank you once again for your help. Typical of Glocals friendly and helpful service.
