its most likely your digital meter.
my fluke i use at work will not properly
read a field winding above a 100 ohms due
to inductive reactions. it just sits there
blinking now and then giving me an OL reading.
try putting it on DIODE mode.

Having an open resistance reading on the primary in indicative there

You obviously missed the point, which was that a finite resistance
could be measured from the center tap to either end of the primary but
that the end-to-end resistance was infinite.
