It definitely looks like a Quintron constructed board.? The white label with the writing on it looks like how they identified boards. The date code may be 1989?? I think that was before they were bought out by Glenayre.? I've worked on several pieces of Quintron/Glenayre equipment but don't remember this board, especially one that had a BNC pigtail on it.? The pigtail looks like it was factory installed and not a modification, unless someone did a nice job of modification.
