One is Calido Guitars in Texas. That's who I was discussing the F 40 GSR with inititally. He had 2 naturals and 1 burst GSR's. I decided no on all of them. As far as I know he hasn't put any of them yet on his website. He's likely a bit upset with me. I told him initially I was all in but when I saw the little difference between the F 40E T and the GSR I backed out. I also bought my F 55E GSR and my BT 258 Baritone from him.I have not sees 3 others (where?) but at least one more, and just one serial number apart from one of the CME ones!
Guild USA GSR F-40E Traditional Satin - Antique Burst
This is a one-off GSR (Guild Special Run) model that we were fortunate to acquire. Based on the F-40 Traditional, but with a super-thin satin lacquer, gold tuners, an LR Baggs pickup system, and a handcut celluloid pickguard, this is a true one of a kind piece that looks and sounds fantastic...harrysguitarshop.com

Another was Bearded Monkey Music out in Washington somewhere. That's where I bought my F 40E T instead of the GSR. They at least had the D 40 GSR and maybe the F 40E T GSR as well.
I can't remember the 3rd but it was out there somewhere.
