This assumes you never find a cross reference.

The first thing to do is see if you can find the connected end by removing the broken parts. If so, try measuring the remaining inductance (not connected across resistor).

If not, rewind the rest of the coil and count the turns. Then rewind with roughly the same size wire with an estimate of the number that got ruined.

Lacking anything else, try inductors in the range 70 to 390 uH across 39K,
and use whatever you think looks good. These things are noncritical
and are often tuned by eye by the designers. Ideally you look at the horizontal
sync pulse waveforms on a scope.

100 to 150 uH probably will work fine.
