Right just for the record there was a non chrome version quite rare
introduced since chrome was hard to get in wartime. Those where gray paint. As to Leitz Eigentum there is such a thing Leica had cameras set aside for testing purpose in factory, the lettering looks right but its so easy to forge any jeweler can do it in minutes.
The IIIc comes from the number 350 000 til 425 000 and the step on this one also looks right. My opinion is this is a somewhat clumsy attempt lifting value to the level a gray paint would have.
The IIIc is sold for around $ 300 - 400 US in excellent condition .
As I said Charles will have the answer , I send you his number in private.
