Just found this while perusing the AWM website - I've never seen this photo of a 453 Sqn Buffalo before wearing the codes 'TD-Y'. Alas, I don't have the serial number tie-in but we might be able to work that out based on the accident record cards. Anyhoo...it's a lovely pic, and a rare one in that it shows the upper wing surface of a Brit Buffalo.
Then I found this pic of 'TD-U'. I need to check my records but I'm 99% certain I can find a serial number for this one:
