The shift knob on my '37 P4 coupe is definitely not an original. The threads on the shifter are much smaller than the threads in the knob, consequently it keeps coming off in my hand.... It does look period correct though.

Does anyone have a picture of the shift knob that would be on a vehicle of this vintage?

Coupla wraps of duct tape on the shifter oughta work.

if ya can't fix it, duck it. Right? ;-)

Might follow Mr. Adam's advice and get an insert or turn one myself.

So, the shift knob I have is 3/8" x 24tpi. And as it turns out, 3/8" x 24tpi is the size tap for a 5/16" x 24tpi helicoil. That's the thread size in pitch on my shifter ....

BOOM!
