Help ID'ing a PDP-8/A Omnibus board

[systems_glitch]

>From the layout and text font, I'd guess Sundstrand (CNC machine company)
but usually they put their logo/name on boards. I only have Unibus
Sundstrand boards in the shop at the moment, but none of them have that B
logo. Wouldn't be surprised if the B logo is from whoever made the boards,
as in the actual board fab house.

Thanks,
Jonathan
