Hi 37 Cord,
That would help.
Yeah, I doubt that any part of the oscillator coil should be in the megohm range. most windings in oscillator coils read under 25 ohms or sometimes less than 5 ohms. I am hoping that the break i at the "top" of the winding, right under the tickler.
The wax can be melted off the coil by heat gun (be careful) or in an oven set no higher than about 200 degrees (be careful that the Wife is not home, of course).
if the break is found and is not under the tickler, it can be spliced. In fact, there are supposedly instances that this occurred in production during the early 1930s. When the spool ran out in the middle of winding, they merely spliced the beginning of the next spool to the unfinished coil and finished the winding. However, each winding was a single layer back then, as the coils were rather large.
Attached is a You Tube video of troubleshooting an oscillator coil on a Philco 37-600 radio:

Does your coil look similar or does the tuned potion of the coil look more like a tire?
