Or you could wind your own...really no reason to use E laminations
you have a lathe...simply trepann out the coil cavity, leaving a
"post" in the center drop in the coils and screw on a round cover to
complete the flux gap

This is why transformer cores aren't solid iron:

"Early transformer developers soon realized that cores constructed
from solid iron resulted in prohibitive eddy current losses, and their
designs mitigated this effect with cores consisting of bundles of
insulated iron wires."
