Hi
I have about a dozen Narco MK12 displays. I don't know if there is a difference between the D and E models.
They came from a closed Avionics Repair shop. Most look pretty good, but I have no way of testing them
I will guarantee one that works. If you plug it in and it doesn't take a picture, E-mail it to me, and return in 7 days and I will send you another one...
They list for over $350.
