IMHO, cast repairs using brazing is the simplest method of repair i can think of.
braze the missing section up with a flux covered bronze brazing rod like Harris LFB, with the oxy-acetylene rig if available and grind it flat, use a flapper disc to smooth it out.
slam dunk, really.
BTW, we don't care if it's steel or cast iron for this repair LFB brazes both!
LFB taps like a dream and can easily be machined if so desired.
if you use Harris LFB coated rods the tensile strength is 65,000 lbs-
not too shabby for an easy to use rod. i'd suggest a 1/8" rod for the work as pictured, you can use smaller rod but you'll be there for a little while longer ..
good luck in whichever method you choose
