I see 1/55 styled shins and feet on the left black robot, and on the right silver robot, 1/55 styled arms and what looks like exact 1/55 front landing gear, with the nail buster release switch and spring.
For the center f-14 I just see the tail fins can collapse (to the outside, not over each other), but I'd call that a strong derivative.
Anything else these old eyes aren't catching?
Cool find!!
