The first pic was one of several different Lancs used as test beds for
turbojets or turboprops after the war (note post-war colour scheme and
roundels; this one was, I think, a Lancastrian I, with Rolls-Royce Nene
motors in the outer nacelles). The second was a Lanc B II, with Bristol
Hercules engines. That particular machine has a bulged bomb-bay and a
daylight camouflage scheme. It might, I think, be a post-war pic of a machine
on maritime recon duty, carrying depth charges, anti-submarine torpedoes, and
a life rift in the bomb-bay. I can't tell much, the pic has been edited to
remove the squadron identification markings and the serial number.

Other Lancs fitted with jets included a B II which flew as a test aircraft
during the war, with a jet in the fuselage.

Note that the specs on the page are for a B I, when the top pic is a B II.
Note also that they spelled 'Nene' as 'Nean'.
