Below are some notes I collated when I built my Mk 40 - covers 1944 in particular.
The notes are drawn from a number of sources for my own use and I hope they assist? There's a lot of info available on line (including BM) if you seek using the below references/serials.
DH98 Mosquito
Agreement between De Havilland Aircraft Company and the Australian Government had been reached to manufacture the Mosquito FB40 for the RAAF at Bankstown but serious delays in production meant that the first Mosquito was not delivered until 23 Jul 1943, entering service in Mar 44.
Six FB40s were converted into the photo reconnaissance role and delivered as PR40 model, retaining their original serials: A52-2, 4, 6, 7, 9, 26. All went to 1PRU with the first delivered in May 44 (A52-2). Operations soon commenced with nine sorties in Jun by A52-2 completing the longest mission so far to Balikpapan in Borneo (2,235 miles round trip). A second Mosquito A52-4 arrived in Aug 44.
These aircraft operated so effectively that a further 28 FB Mk 40s were converted to PR Mk 41s and renumbered A52-300/327 (ex A52-90, 192/211, 41, 45, 49, 62, 64, 83, 36 respectively).
On 10 Sep 44, 1PRU ceased to exist and was reformed as 87 Photo Reconnaissance Sqn.

Flew nine PR missions during August.
01/06/44 AWM photo P002448.075 shows A52-2 landing at Broome WA after this flight. It captions the crew (FOFF Ken Boss-Walker and Nav POFF Jeff Love) as also having been the first to complete an operational flight in a RAAF Mosquito to Ambon on
25/06/44 Pilot FOFF Ken Boss-Walker suffered an engine failure over Surabaya NEI (Netherlands East Indies) and flew the 10.5 hour return trip to Australia of 1450km on one engine.
Presumably, this is the rationale of the name of ‘Old Faithful’ painted on the port nose along with thirty-eight mission marks (Photo: Pentland Vol2 P.100).
A52-2 was also detached to Leyte in the Philippines where it suffered hail damaged to the wing leading edges (Wilson p.184).
