That's completely bogus. There are signal message exchanges between AHQFE and Mingaladon asking about the status of their intelligence holdings, with specific mention of intelligence about the A6M. Mingaladon responded that they had received the information. There's also traffic from 67 Sqn noting that P/O Wigglesworth, one of the pilots, had been tasked with the secondary duty of Squadron Int Officer and that he'd set up an intel table in the squadron ops room where all pilots could access and peruse available intel.
AFAIK, the actual source of the "locked in a draw" comment has never been discovered. It sounds like hearsay and is certainly not supported by (the admittedly limited) available files in the UK National Archives.
I don't doubt you. While I don't know enough about the matter to argue his claim, I defer to your knowledge, sure.
He has a smug and smarmy mien that inspires distrust in me, but I watched to entire show anyway.
