>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.
