Found another Ref. 3006 out there

It was sold back in December on Ebay. The hand set and date wheel look incorrect, but regardless, it is nice to have photographic evidence that another one exists. To date this is the only other Ref. 3006 I have ever seen. I hope the winner wears it in good health, and maybe even finds their way to OTD.
