There is much in Wynn if you read very slowly cross-referencing multiple entries. Do that and: when Press were shown hastily camouflaged Vulcan 2, 2/63, some Blue Steels were visible. 6 were formally taken on charge by the Scampton Wing 28/3/63 as acceptance trials vehicles. Clearance was given to carry them inert. On 16/4/64 CA Release was given to drop live at high level, initially 617 Sqdn, 27 Sqdn mid-1964, 83 Sqdn, late-64; in February,1965, to release at 12,000ft.; later, Vulcan 2, lower (Wynn,P.460).
8 Finningley SSA Yellow Sun 2 were available to Scampton Wing Vulcan 2 from 7/61 to early-63.
So: no, no Blue Steel involved in October,1962.
Wynn at one point implies BS was never cleared for QRA, but Pontius, in a long gone post, suggested eventually it was. Heating, HTP, pain.
