Frank,

Thanks for the claims details. Any times for the claims?

From the Navy List for August 1941:

Ball Lt.(A) RN
Hutchinson ASL(A) RNVR (Acting Sub-Lt.)
Park Sub-Lt.(A) RN
Prendergast Lt. RN
Reed (not Reid) Lt. RN
Stewart-Moore Lt.Cdr. RN

Often I find that regular RN officer aircrew did not have the (A) appended to their ranks. Most likely the petty officers would be designated PO(A) as well.

Cheers,
Tom
