Thanks Dave and John. It appears quite possible that I came to a quite unwarrented conclusion regarding the identity of Armstrong. Taking another look at the Paradie Archive
http://aircrewremembered.com/Paradie...eArchiveA.html
I find the following for H.
S. Armstrong (J16531):
RCAF 21 Aug 40
1 (RCAF) ITS - 11 (RCAF) EFTS - 1 (RCAF) SFTS
59 OTU - 135 Sqn 15 Sep 41 - 31 May 44 - Europe and Asia
17 May 45 - Released from the RCAF apparently as a Flying Officer
26 May 51 - Rejoined the RCAF - 25 Apr 56 - Released from the RCAF
According to The Canada Gazette (v.77, n.15),
Homer Scott Armstrong was commissioned from F/Sgt. (R68585) on 14 Nov. 1942. So he could very well have been serving with 135 Sqn., as John points out, in Oct. as an NCO pilot prior to his commissioning, unlike H. A. Armstrong who, as Dave points out, was still in Canada in Nov. 1942.
So now I'm thinking that Chris Shores in
Aces High and
Air War Over Burma may have gotten the initials wrong. John, is there any further indication of his identity in the 135 ORB?
