Hi ghensgen, I know it's not exactly what you're asking for, but if it's any help, I've still got (most) of the original decal sheet from the Tamiya Lancaster from 30 years ago! I didn't use the code letters, as I hand painted squadron letters for the aircraft of a friend, who the model was for. I haven't got them in front of me, but I seem to recall that the aircraft were Gibson's 'Admiral Prune', and the famous 'S for Sugar.' If they are any use to you, you are welcome to them, no charge.
