Input transformer question

[ReRibbon]

Hello,
I've got a few old Belclere (Neve) input transformers whose pins are unmarked by number. The transformer is tge 8260. It has 4 pins primary, 4 pins secondary,  and a ground pin. On the primary, I was able to figure out tgat the two middle pins get 25 ohms.
Can anyone please walk me through how to identify the rest of the readings?

This would be something I had never thought of before.
