Well I've got an update for those who were wondering about this; this is 100% factory done

.
It took a bit of work to get into as I fashioned some tools to get into it without putting a scratch on her. Once into it I can happily report that this is 100% matching

.
Now for the good stuff.... the swept grip is mated to the frame with a retaining pin. There is a inspection proofmark on the retaining pin holding the custom gripstrap, which by European proofmark law would have only been added by the factory. To add to the fact that the pin is proofmarked it has been permanently placed (I assume brazed but I can't really tell, it's incredibly well done) into the pistol in that everything is blue around it while the retaining pin for the grip is still "in the white" and bears the inspectors proofmark that can also be found on various pieces of the gun. There are no tell tale signs of a refinish at all, this is 100% factory done, fully matching, and near mint.
Lots of work put into this one, but I'm very pleased with the result
