Knowing the mysterious ways of the RAF, I suspect that the medals will hopefully turn up with "someone" to ensure they "fit" properly. It doesn't forget those members of it's family who put life and limb on the line and I do hope they take due note of 1291451 RB Carpenters' birth date!
Have you also been able to contact the Sqdn's Association?
No. 10 Squadron Association, c/o D. Dent, 145 Stanks Drive, West Yorkshire LS14 5NU who might like to help......
