Dave Winspear from Whitby in England sent some further photos in late 2003, taken by his brother Mark. This is one he took in France showing how an R4 can easily be converted into a handy trailer. A similar example can be found amongst the pictures from the museum in the R4 40th anniversary report from Arnhem. You can find the other snaps from Mark in the People's Pics section of the Gallery (number PP135).
