Regarding de-icing the inside of the transparencies of the Meteor our local mod was a small canvas bag attached to a suitable place in the front cockpit which contained on a piece of string a small sponge from a dinghy pack soaked in glycol. The other alternative was to romp around for a few minutes at low level and high speed (400 kts-ish) whilst watching the fuel gauges unwind !
On one occasion the pitot heater failed and the asi and the vsi (or should that be, for the politically correct, rcdi?) gave up the ghost above some embarrassing cloud whilst I was conducting an IRT. We let down using the flap indicator which, if 1/3 flap was selected, showed the flaps being blown back up above 230 kts or so. The cloud base and fuel state were fortunately sufficient for a high speed romp around North Devon to thaw the ice before joining the circuit.
Those of us familiar with Hunters will no doubt remember romping around at high power and low level with as much flap, airbrake and u/c as could safely be extended to burn off excess fuel to get down to max landing weight, which if you had two 230s, 2 100s and 560 rounds equated to min circuit fuel. Happy days.
