It's Wallis not Wallace.
Years ago, I was proud to provide a radar service to a Vulcan fron 617 Sqdn (what else) doing a flypast at the great man's home for his birthday. Years earlier (about 1965) I went on a school trip to Weybridge/Brooklands where we were shown into his work area in the racing circuit control tower (which is now part of the museum) and they showed us models of his VG designs and told us he still came into work occasionally.
