Yes, there seems to have been some confusion here, sorry. I was aware that the link I posted was to the F3H-G/H. I was using it only as a comparison to the original post photograph, in which I was mentioning that the second cockpit canopy could not be seen, or at least was not clear. Because I did not see it I was really questioning if this was an early F4H.
I have since watched the linked video and see that it is indeed the F4H-1/F-4A mentioned. It is a testament to how low-profile the original second cockpit canopy was that it can so easily be overlooked from some perspectives. D
