It's going to cost £105 to have another caseback engraved and tested but my dad's service No. 2226899 seems more personal than the kite's Squadron letters he flew in a few times.
I can remember as a kid him telling me his Lancs letters but very little else.
He didn't mention for instance that other crews had been lost in their previous QR-T's
Looking at his mate's logbook copy they flew in most of 'B' flights Lancs anyway.
