I think that they have to be Z57xM. I found an easy way to tell if a tube is RFT made or not - RFT made rounder digits, and number 6 is the easiest to see. Every other tube I have seen has 6 consisting of a circle and a straight line, while RFT tubes have 6 made of a circle and a curve. On photos provided by the seller we can clearly see the curvy 6.
By the way, does anyone know where those panels might come from? It is not the first time I'm seeing Z57xM display cosisting of vertical PCBs with single tube.
