Bell Aircraft control box?

[OldGeezer]

McDonnell's XP-67 had what appears to be a camera control box in its cockpit, which isn't unexpected since its flight testing involved filming of instrument readings. But this unit was made by Bell Aircraft, and I'm wondering if anyone can confirm that this is in fact a camera controller and what other aircraft might have used it. I've been in touch with today's Bell and drew a blank, and my own searches haven't turned up anything either.

It may have been a "one of" box for the XP-67 and not used anywhere else.

E.G. like this box in the Spruce Goose made by Hughes, S/N 1 & S/N 2 right across from each other.
