It doesn't matter, with cut side down the top two pins are ALWAYS the field coil.

In your case:

If you look at pins from the front,

P1-P2 are field coil.
P2 is also the center tap of the xfmr primary.
E and D are the Pushpull ends of the primary.

Or as Arran suggested: it is grossly miswired.


PS. It is also possible that whoever fixed the radio the first time also miswired the chassis socket and then wired the plug to fit.
You have to see what chassis is like.
PPS. I'd still made the wiring standard lest you one day burn a perfectly good speaker plugging it in your chassis.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
