Yes such terrible news about Chris, I was only in touch with him the other week about a replacement smokebox dart for my Minerva pannier. I had broken one of the handles when fitting the smokebox number plate, he told me to send an SAE and he would forward the parts FOC. True to his word two sets of spares dropped through my letterbox a couple of days later. I didn't know him well but had always enjoyed his articles in RM, he came across as a real gent, and is a real loss to our hobby.
RIP Chris
