Sorry I can't be a great help, but from what I gleaned about Universal cabs, the usual suspects include Toei monitors, maybe a CM R14? I find that sometimes cocktail monitors are described as 14", so you may want to through that info into any search terms.
My Universal Cosmic Avenger had a 19" NEC in it. That being said, maybe you can find out what monitor used the tlf6036f flyback and narrow it down a bit. Is that a Mitsubishi Logo on that flyback sticker?
