I am trying to identify the six Lancaster B.1 (FE) that were on charge of No 35 Squadron during 1949 before it re-equipped with the Lincoln.

I have tracked down four (TW657 TW660 TW865 TW880) but wondered if anyone else has any information on the missing two (working on the basis that the squadron was working at establishment number of 6)

I also know that TW657 was off charge of the squadron following incidents in January and October of that year (1949) but have no information on why .... any help on this matter would also be appreciated
