According to Vickers' own figures, the 21, 22, & 24 had a maximum speed of 450 m.p.h., at 25,000'; although not a fighter, the XIX had the same rating.  Seafire 46 & 47 were the same, but at 20,000'.

For high speed testing, the flying tail was fitted to the fastest aircraft available, a Supermarine Spitfire. RAE test pilot Eric Brown stated that he tested this successfully during October and November 1944, attaining Mach 0.86 in a dive from high altitude, thats 654 mph

by the way i wasn't igmoring drop off, Brown dove from altitude to get the speed, your figure of 660 mach makes an altitude of 45000 feet. It would be tough to get the old spit into a mach dive above its service ceiling. I never mentionedpTowles getting a mkxix to 690mph in 52, though it was by accident and not what you might call flying.
