Having just scrutinised the wonderful cutaway drawing of the Lancaster (done by Jimmy Clark during WW2) in my copy of "Classic WW2 Aircraft Cutaways" by Bill Gunston, I can report that the only ice protection to be seen on the aircraft is the pair of 'Anti-Icing Glycol Window Sprays' in front of the cockpit screens.

Avro York (derived from Lanc.) unsurprisingly, had same 'windscreen washer' de-icers. However, US B-17 and B-24s were fitted with 'Boots'. It seems that there are records of experienced B-17 crews in European Theatre having the 'Boots' removed as they caused both drag and flutter when they had been shredded by 'Flack'.
