It did indeed come off the chassis of a Philips 795A mark, but I don't know if it was an original item or a later replacement.
Alan, I think you must be right that winding 2 is the primary. I had a look at the link Mark posted to the 795A on RadioMuseum and it mentions Power type and voltage as (AC) 100, 125, 145, 200, 220, 245 volt. I don't know enough about power transformers to work out how each voltage would be accommodated from winding two, but I'm guessing it can be.
If winding two is the primary would this influence the voltages off winding 3? I'm guessing it almost certainly would if 100v was selected. The ratio would be the same right? But with 100v being at 41% of the 240v that would give circa. 500v and 250v off winding three I think.
