That not a Lancaster..it a Halifax Mk1

[ImJustAnotherOkie]

AS you can see the Lancaster pictured here does not have Radial Aircooled engies as it is far too streamlined.

1. Cockpit top at same level as fuselage, triangular endplate fins to tailplane - definitely Halifax (Lancaster's were raised above and elliptical)

2. MkII (Mk 1 had no mid-upper tuttet)

3. Radial Engines only came with the Mk III (the more numerous version)
