Thanks for heads-up with regard the colour G, i've got 4/5th's of a tin left at me enamel sprayers after having a fork and stem done a while back, been busy since but i'm so enamoured with it's classical look that the frames going in shortly (your pic's/posting have sent me over the top)
The old fella had an Ro80, there was some debate arround how to factually gauge it's cc, with some quarters stating 1litre and others 2llitre because of the delta shaped melarky...which seems odd in that the factory decided to put an 140mph clock on the dash in '67..had it down to chester @135mph but it was lifting dramatically, could get 60 out of first gear...the more you tanned it the quieter it got, could'nt hear it after hundred (nothing-strange sensation).
Seem to remember a tv show with a couple of DS ambulances in it..for now it escapes me.
