Many thanks.
“Glasgow’s Own” by Dugald Cameron Confirms that VW438 was a 602 machine delivered 16-4-1951 and also that he was caught by an East Coast Harr. Much like today where the haar is sitting across the mouth of the Forth.
603 was at Leuchars as Edinburgh Turnhouse’s runway was being extended to enable Vampires to land. Although they had received 3 Vampires at Leuchars and perhaps the Meteor had been borrowed from 602 to assist with conversion training as their own Meteors arrived around July
