The Gods have been kind. I peeled the paper covering and very gently teased open to the solder joints between the leadout wires and the coil winding. the break was right there, and enough wire remained to allow the connection to be repaired. Field coil now measures spot on the 2100 ohms on the rather fuzzy schematic.

Edit - the difference between mode l651 abd 662 has been revealed. 651has shortwave coverage from 5500 to 18 MHz, whereas 662 covers 1600 to ~5200 kHz. Otherwise, they are the same.
