No idea if it is who you are looking for but I’ve done a lot of drooling on @Mr. Smith’s work a.k.a. Superior Firearms LLC / Joe Barnsfather

Actually I think that is the place! I looked at their photo gallery and although I didn't see a 640 with rear sight, I remember the photo I saw was also against a tree background like many of their photos are done. I'm going to drop them a line this week. Thanks!
