I know it's a long shot but you never know.
I knew JC at CAD Kineton 1983 - 1986 at which time I was posted to Germany and we lost touch. We had some great times in the rugby club and at his place in Newbold-on-Stour... over the river cricket and tug-o-war against the women & tractor lol
Prior to Kineton JC was at 4 ADOC, and he came from Rochdale. Not much to go on is it lol.
If anyone has any info I would dearly like to get in touch with him again.
