Ted: Based on appearance of wood and finish in both cases, I have no reason to think that the shaping on either the Charlin or the Merkel is other than "factory original". I've put this bit about built-in cast in play previously (including fotos) and have not been greeted by resounding Hosannahs of instant recognition. No reference by Mr. T to a practise of shaving the comb off the centerline or sweeping it in a curve that I've heard. Perhaps M. Gournet should be queried about this! Either a lot of folks are too busy to notice this OR I don't know from s--- from apple butter?
