Your information may be more reliable than mine as I can't find my sources at the moment but I had noted in the BSAA fleet list on my website that the aircraft (a Lancaster remember, not a Lancastrian in this case) had been fitted with a Lancastrian style nose by A.V. Roe at Waddington. It had originally been loaned to BSAA and was only bought by them at the end of March 1947 when it was dismantled to be used for spares.
