I would be interested to see if any of the above survived in one form or another :-
JCW97N - Feb 1975 RD350A - bought as a standard work hack from a guy in Great Sankey Warrington in August 1981 - came with some wonderful extras including a bikini fairing with voltmeter and crash bars wrapped in black tape

By the time I went to work on it the next morning most of it was in the bin. Kept in 4 years until August 1985. Standard burgundy paintwork and was still 5 speed. Painted frame red and fitted centron expansions (owned by Micron if I remember correctly), K&N's, Boyesen reeds etc. 2:4 style seat off coffin tank model that we had to cut the foam down. RD400 back light and mudguard, XS650 front mudguard and T bars!!! Think it was last on the road in 1995 and a v5 issued in 2013 but since then the plate is now on a transit van

XVR806S - Jun 1978 RD250DX in silver with wire wheels. Bought in Jan 1985 paid £35 for it when nobody wanted 250's. Kept it about 6 months and then someone offered me £50, so sold it. Last on road in 1991 and was white by then.
NNF106W - Sep 1980 RD400F in white. Bought in Feb 1985 for £200 and kept for a year or so and sold for £250. Ex-proddy racer with various bits still wired up. Microns and 2:4 style seat in red and blue. Sold to mate who sold it on again about 6 months later to a guy in Chester possibly in the Christleton or Littleton area. Last on road in 1987. The one I wish I had really kept!!
Any information greatfully received, cheers.
