the shipping label was in my mail this morning, so I'm off(shut up, Og) to the shipper.
Just for the timeline:
Wednesday evening: extractor failure(and disappearance)
Thursday morning: call S&W, "You'll get a label within 48 hours"
Late Thursday: take one last look before boxing it up and Lo! found the extractor; tape it and spring to the receiver
Friday morning: get label and take it to FedEx.
So a few days to get there, this time of year no telling how long to get to it. We'll see.
