I've worked out the ratio as 42 to 1, the output valve is AC5PEN, 5200 ohms into a 3 ohm speaker. The one that someone has lashed in is 52 to 1 and too big to fit in the frame.
It needs to be a round 430 ohms resistance on the primary, so a small gauge wire will be required, maybe 48swg.
The mounting frame is very small, I will have to strip it out and measure it if I can find time, I doubt I have a transformer with such small laminations.
