Sorry for your loss!
I'll mention a few things. Short of finding a replacement coil you could use a 2.5mh choke to act as the open winding (only it's not open) and use a small cap to couple the rf signal to the secondary of the coil. The primary is untuned. Operating the set on that band with an open plate circuit may damage the rf amp tube's screen grid as there is very little plate voltage. The screen grid at this point is acting as the plate in terms of dissipation and is not designed to dissipate very much.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
