I don't at all see Vernon Felix LaBrayere (338 53 54), ARM2c (CA) V-6 USNR on any enlisted roster I have for VT(N)-91.
On the other hand, I have him showing up as early as 1 December 1944 in VT(N)-52 war diaries and on through the end of the war. From that I would guess that he was not in VT(N)-91.
Subsequent appearances on VT(N)-52 rosters are in the monthly war diaries for
December 1944, dated 1 January 1945
January 1945, dated 1 February 1945
February 1945, dated 1 March 1945
April 1945, dated 1 May 1945 (and with promotion to ARM2c from ARM3c)
June 1945, dated 1 July 1945
July 1945, dated 1 August 1945
August 1945, dated 1 September 1945 and
September 1945, dated 1 October 1945
The squadron War History, dated 1 November 1945, shows him (fourth from the bottom of the page) as received on 20 October 1944, the day the squadron was established and, as of 1 November 1945, still aboard. See page 2 of the enlisted roster from that report, attached.
