I am referencing the schematic provided...
IMHO only a replacement (Philco) RF transformer for the BC band will be a drop in fit.
Alternately it can be rewound.
Although the schematic is just a line drawing of the RF coil, it appears to have a combination of solenoid and universal winds.
Stated, the primary is open, that could be the universal wind.
It is possible to scramble wind that primary as it is not tuned.
Scramble wind is a compromise, best advise is not to compromise on any other coil parameter such as the turns and wire size & type.
A Morris winder could reasonably replicate the universal wind...
