Got it. The cruel irony is that there are 3 odd ones out, actually, dear chap: TR, BL, BR because - unlike TL - none of these are direct cousins to Shorts 330 G-BITX that Mrs and I flew to Guernsey on for a holiday in 1982. I thank you! (Stands looking smug and expectant.)

Bob... we need to have words.

Bob, wouldn't that make the OOO be TL because it's the only one who's cousin you and Mrs Bob used to get to Guernsey in 1982, or am i overthinking this? Pedantry aside you deserve to look smug about it.
