The only functional difference compared to Regula IIb is the film speed memo on the rewind knob. Thus it is even more interesting that both models were produced simultaneously and I would really like to know what the original price difference of the mentioned models was. Other than that, the Regula IIIa looks a bit neater due to the black King logo and black paint filled stripes on the front plate.
