Hi Rog1 and Glenn
Not sure about the front mudguard, all I can tell you is it has a Claude Rye badge on the front edge. The side stand is as you say. I presume my friend Fred fitted it because when it was loaded up for the trip, it would have been the only way to stand the bike. I have to say that I was not comfortable with it so I have removed it and fitted a rear stand.
Yes Glenn, the oil tank was enlarged to increase capacity. The rear footrests were modified to facilitate the fitting of some home made panniers. A dual seat was fitted, and the air filter system modified. They had one breakdown on the trip, a puncture in New Zealand that required a new tyre and tube.
