Hi and welcome,
This is what I would do. The primary isn't part or the tuned circuit it's just there for coupling. The number of turns isn't particularly critical. One of the thing we do know is that it's 25 ohms which works out to 25' of #40ga wire. That should get you close to what you had. If we didn't know the resistance I would measure the diameter of the coil and rewind it to the same size.
GL with your new project!

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!
