Big E is either 1/720th or 1/700th
I have A-6's and A-3's. I have a ton of unbuilt Fujimi 'Nam-era birds (Crusader, Phantom and Skyhawk). Vicky came with 24 birds and also the Fujimi RN set which has 32 birds (8 Gannet, 8 Seafury, 8 Wessex and 8 Seafire). I'm doing her during the "princess cruise" when she travelled the empire with HMS Vanguard. Vanguard of course had princesses Elizabeth and Margaret onboard.
We're talking late forties - '47 I believe. Right before HM Government publicly went broke and started scrapping the RN.
