"Lizzies"
Warmtoast.
Could be wrong, but the things tucked on to the bombracks don't look like 250 lb bombs to me (no tails, for a start). LR tanks more likely.
They did a mod on them with a twin tail and a rear 2 (4?) gun turret between. Met a chap once who'd flown 'em. Said they (the modded ones) were pigs to fly !
Can't see that they'd get much lift from those stubs, can you ?
