Prompted by Barry Boor, I found this obituary. I have no further information:
Was unexpectedly taken away from us far too soon on 15th August 2015. Wim, beloved husband of Thea, a much loved Father of Jan-Willem
and Willem, a very dear father-in-law of Wendy and humorous Grandad of Harmony, Prudence, Xylia and Xalvador. He will always be fondly remembered for his success as the founder of racingmodels.com and his passion in the motor sport industry.
