They're quite fantastic actually. Haven't seen a set in hand in nearly 20 years now.
No pic of the back but I suspect they are Gibson branded Schallers and not Grovers?
Here's a set on a Custom I had, but no pic of the back, but of the back on a Silverburst I had and they are very much the same tuners Guild used, with a Gibson tulip button, so quite possibly the fold out tuners are Schaller.
