The history of BR169 is as follows
2650 EA FF 7-3-42 8MU 15-3 82MU 25-3 Emp Hth 29-3 Tak 4-4 Malta 8-6 603S CA ops 17-5 FACE 18-8 SOC FH68.25
The Emp Hth would be the ship "Empire Heath". "Tak" would be Takali, Malta. Others may be able to help deciphering, as I'm not familiar. The squadron code for 603 was XT. 603 only existed on Malta for four months, for the remaining crews and aircraft were incorporated into 229, Code HB or X, which itself reformed as 603 in Jan 45.
