With regard to St.G76 use of the Griffin emblem, the Director of the EOE project stated this in a recent post at TOCH on the subject:
"I just did a quick run through of examples of I./StG 76 images in our DB (51 of them) and this insignia appears to have been universally used during the WC Blitzkrieg of May-June, and there are a few examples of it with the 1939-style fuselage crosses which presumably date back to 1939, and likely to the Polish Campaign."
It is really a shame that Heinz Migeod passed away two months ago before this discussion/thread arose. First hand accounts and memories surely superceed a stack of supposedly well-researched books,or tertiary research derived from such secondary books/sources.
He was
there, he flew with 2./I./St.G76
and 2./I./St.G3; his Flugbuch clearly shows that he was flying his Ju-87 Stuka S1+DK in June and still flying it on 10 July a day after some Luftwaffe orders had been published redesignating his unit as 2./I./St.G3. It is very difficult to believe that he and his Staffel mates would have removed their St.G76 griffon emblems in the midst of an ongoing battle/campaign, then at a later date
after their less than one month involvement in the BofB,
re-applied those same emblems as the unit re-deployed to the Balkans. Heinz in his interviews made no mention of any such 'temporary/interim' removal.
