Ghetaldus Zagreb King Regula IIIa

For introduction to Ghetaldus Zagreb cameras, see Ghetaldus Zagreb King Cameras page.
For information on specific camera models, click on these links: Regula IIb, Regula IIIa, Cita III, Regula L, Regulette.

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.

Regula IIIa Ghetaldus Serial Numbers

In the table below there are all serial numbers known to me. In case there is a "*" symbol besides the Variant, the variant is an educated guess due to a lack of data.
