well koodoos to you for identifying it. when I first saw the one hole on the side I was leaning towards a Kommer III but that base plate is would not be correct. as for value. that is tough. I was told by Jim Schaffer once that he has more trouble selling rare mags then the common ones. he said just as rare as the mags are so is the finding the person that needs one LOL. So, keeping that in mind, I would think $100 would be a fair price. its not overly expensive yet is a little premium over say that French unique mag you referred too.
