Re:56th Weather Reconnaissance Squadron of WW2
According to Mauer-Mauer Combat Squadrons book, the 56th Weather Squadron first came into being December 1945, having previously been a fighter squadron:
LINEAGE. Constituted 358th Fighter
Squadron, and activated, on 12 Nov
1942. Redesignated 56th Reconnaissance
Squadron (Weather Scouting) on 3 Dec
1945. Inactivated on 20 Nov 1946. Redesignated
56th Strategic Reconnaissance
Squadron (Medium, Weather) on
22 Jan 1951. Activated on 21 Feb 1951.
Redesignated 56th Weather Reconaissance
Squadron on 15 Feb 1954.
The stations listed for the later years are as follows:
16 Jul 1945; Schweinfurt, Germany, Apr
1946; Mitchel Field, NY, 1 Aug-20 Nov
1946. Misawa, Japan, 21 Feb 1951; Yokota,
Japan, 14 Sep 1951 (detachment
operated from Andersen AFB, Guam, 11
Mar 1960-18 Apr 1962)-
This publication also suggests they didn't have B-29s until starting in 1951, and were unequipped between P-51s up to mid-1945 and 1951.
So your B-29 had other assignments earlier before the WB use.
