As bobouz has suggested above, I'm like 100% sure that's not the case. Someone has done some amateurish modifications to the guitar. The top looks stained as if to match the mahogany of the rest of it. Also that's a Taylor pickguard if I'm not mistaken, which could've come on the top and he just retopped the guitar. Without having the actual guitar in one's hands it's nearly impossible to tell what's been done. I don't know of any factory Guild was in that would've allowed work like that to go out. And remember that Cordoba Music Group now owns Guild but when it comes to Guild history you've got more knowledge here on this forum than probably any other source. The inlay around the rosette is the most telling thing of all. This was not done by a professional and I've cropped the photo and enlarged that portion. In my opinion it's the original top for that guitar (Sitka spruce) but you can see the inlay work is done poorly. One ring of mother of pearl and one of abalone? No one does that. and then added a Taylor pickguard to go around it. Guild for sure isn't doing that!
I think what you have is an old Guild F-112 as Kurt said, that's been heavily modified by its owner, who also added the abalone dot fret markers. In addition to the JBL Bridge Doctor someone has used some type of nuts and bolts to help keep the bridge in place. I can't see how it's done on the top but you can see the screw with the nuts on the inside shot. On the one shot of the top when you make it really big you can see where the holes have been plugged with wood to hide the screw heads. It originally came from Guild but that's where it's association with Guild ended. That's all I can think to tell you.
