How about if winding 5 is a centre-tapped 6.3V heater winding and winding 4 is a 5V rectifier heater winding?
Then the HT would be a much more respectable 312 - 0 - 312 and both windings one and two are the primaries.
Winding 1 would be 120V but in combination with winding 2, would give a range of voltages up to 266V - albeit still with a strange sequence of intermediate taps!
