I don't think so. Apparently this one has been in the guy's safe for a few years. He said it came with Pachmayr grippers, but he replaced them with some attractive faux ivory grips. I picked it up today, and I'd post pics, but I need to find a new photohosting site.
The twist to this story is the guy brought along a 640-1 that has been fitted with an XS front sight. I've always wanted to try out an XS sight, and I don't own an all-steel Centennial, so guess who has *two* new J-frames?
I have no will power...
