FAA crews and the Bismark

[Whenurhappy]

Dear PPruners,

I am on a mission to help out an elderly relative to track down the whereabouts (or, more probably learn of the demise) of a FAA observer who crewed with Jock Moffat, who together are credited with launching the torpedo from a Swordfish that crippled the starboard steering gear of the Bismark. The officer is question is:

T/S Lt (A) J D Miller RNVR 818 NAS. He would have been born c 1920

I've done the usual searches (CWGC, FAA Assn etc) but have drawn a blank from about 1945 onwards. Any help would be appreciated - PM me.

Thanks,

NZWP
