That's the later RF-4 camera nose I used there, with the curved forward facing window. The earlier one has a much sharper angled window and you get both types in the Hasegawa kit. Not only that, you get them in EVERY Hasgawa F-4 kit, even the fighter ones!
I thought the curved one fitted the look of the Lightning better, it almost mirrors the front end of the tank itself, but moved forward a foot or two.
