Colin Lishman a player from Northwood CC is (2021), brother-in-law to Keith Knowles also NCC, and I (KK) recalled him playing several games for RNVR in the late 60s (and possibly very early 70s). He is still alive, I think about 80 years old and living in Llanelli. I don't have an e-mail address for him, but I think that he can be contacted via his son, Jonathan, who is copied on this note.
