Amongst others, take a look at Nos. 255, 256 and 600 Squadrons. All did some intruding, alongside defensive night fighting. There were more Squadrons involved before June 1944 but that's "before my time" as far as research goes.
There's some basic information on the
RAF website. Their Operations Record Books and combat reports are at the
National Archives in Kew, London and extracts can be ordered online.
Equipment by 1944-45 was
Beaufighters and Mosquitoes. There were also USAAF Beaus, Mosquitoes and (by 1945) Black Widows intruding in the MTO.
