WWII RAF bombers with fuselage fuel tanks

Not a bomber, but the Westland Welkin had a 79 gal tank in the fuselage.

In the Halifax, the centre section wing bomb cells and the bombbay. In some instances fuel tanks were placed in the rest bunk area in the centre fuselage.
The Wellington used long cilindrical tanks that were also adapted by 617 Squadron for long range missions which needed the removal of the tail turret and refitting it after the tank had been inserted. (hmmm, can imagine the decal with the text: insert tank here, remove turret first…..)

Same too for the Halifax and Hampden. I’ve no idea how often they were fitted though.

Can anyone name one?

Wellington. The Wimpy could be fitted with auxilliary tanks in the bomb bay.
