See Inside A Hastings
Newark Air Museum (NAM) have one to go inside. It is one of those converted that we trained Navigator Radars for the V-Force before going onto the V-Bombers and I instructed on them. Latterly we trained also Phantom and Buccaneers navigators at 230 OCU RAF Scampton on the radar.
Hence the bulbous radar dome underneath the aircraft. We Nav Radar instructors also used them in the 'Cod War' for spotting Icelandic gunboats (on the radar) harassing our fishing fleet. We used to go on 9 and a half hour trips to Iceland waters and back, detached to Lossiemouth, and also drop mail out of the door to our naval vessels that we were homing in on to the gunboats. Aircraft not open every day as volunteers man it. Telephone Museum to find out when. Trust that helps.
