TFA TLJ Clamp Card

Knowing that most things, down to the T track, were custom made for these films (even the graflex probably got broken down and fabricated for stunts) I always wondered where they got the idea for misaligned card traces. It would have to be something either readily available or available in some professional manner right? (Rpf graflex purchase, Bob's bits, etc)

I have a feeling they modled their card after a Vector 4112-4 board. They are available almost new old stock and they still come in the original bags.

The traces look a bit long because of the angle of my phone but they even match the ESB spacing

Amazing!!
The similarity is striking!
I want to get one to compare it!
But I can confirm that an acrylic version was indeed made by the prop department. If they had these, you wonder why they would do that.

Maybe asymmetrical traces are pretty common?
