So this is a random question. Does anyone out there know of any differences in manufacture for the Pentax 67 left handed grip? The reason I ask is because most of the time I see them with a sort of burnt orange wood grain, however the one on mine is a more dark chocolate almost walnut wood grain and the shape is slightly different. It works just fine, but it just looks different from every other picture I've seen of the left handed grip. Did Pentax change the design at some point? Or is mine perhaps a third party generic grip? Just curious.
