Welcome also nice to have new people on board.  When posting it is also nice for those of us to have a link to the schematic on the thread.  I will post one here so others can review what you have.  I have a feeling that AES (antique radio supply) carries some "universal" osc coils on the cheap.  They do come with instructions for installation in various radio configurations.
Best,  Jerry

Try this link. Smarter people than me can suggest of the two offerings what will work for you. They have worked for me when I had a bad one. Mounting you may need to be a bit creative.

My opinion, for what it is worth ...

Although your radio may use only four connections, the schematic seems to show that the coil itself would have had five connections, but one is not used. I would think that the five pin coil, #P-C70-OSC would be the correct one for you, but only use four of the pins. One end of the tickler is not connected.

Just my $.02
