Specs on Norden M-9B Head Unit?

[Twitchgreen]

I have a Norden M-9B head unit. Unfortunately I don't have the metal shipping base they sometimes come with & have been unable to find one for sale yet. I'm looking for info from anyone who has one. Specifically I am looking for the dimensions so that I can build a replica. Also if anyone has leads on Norden bombsight related accessories for sale I would greatly appreciate it.
