Christopher L. Stuart German Night Fighter Researcher

Chris Stuart interviewed numerous Nachtjagd experten out of an interest in that part of the airwar over Europe. A Dutch researcher who was in contact with him at one time would like to reestablish their previous correspondence. Is anyone aware of whether he is alive and still researching? An address, email, or phone number would be greatly appreciated if you can help me out. Cheers, Jay Hammond. British Columbia, Canada.
