According to the Airtime Publishing book on the F-14, four USMC Squadrons were originally going to transition to the F-14A. VMFA-531 was to be the first, followed by VMFA-451, then VMFA-122, then one more. 531 was actually in the middle of ground school at NAS Miramar, with pilots, RIOs, and maintenance people learning the F-14, when the USMC Commandant cancelled the Marine Tomcat program to free up funds for the AV-8B and the F/A-18. There were a lot of angy Jarheads in the Miramar O-Club that night, I would imagine, and it's probably a miracle that place was left standing. Several of 531's pilots and WSOs, though did finish the transition, and served exchange tours with the Navy. And yes, Grumman did produce a patch:

Będę bardzo wdzięczny za wszelakie informacje,
