Hi,
Sadly I have no photos except what is already available on the Internet. It seems that my grandfather did not take a camera with him to Italy for his second tour. Like you, I have been struggling trying to find suitable references. I have only one photo of BZ965 after the overhaul to work off which shows the mission markings towards the end of its service life. The background in the image appears to be black and I presume this is where the decal manufacturers have extrapolated to come up with the brown, green and black camouflage for the aircraft.
For the interior I have never seen any photos around the fueslage well hatch and unless something comes to light will be basing the interior upon some information I have about the special duties Halifaxes used by 148 and 301 Squadrons and US special operations Librators (search "Operation Carpetbagger" on Youtube for a 15 minute movie about them).
