Mark 33 Gunsight

I'm looking for drawings of the Mark 33 Gunsight as used on the A-26 Invader. Can anyone help?

If nothing else turns up why not try the Air Force or if there's an AF museum try them. This is old tech so shouldn't be protected anymore by secrecy.

Thanks, Potawatomi. I have research requests on this out all over and thought that it couldn't hurt to ask here, too, as there are some pretty amazing collections out there.
