Yeah, maybe it is a diamond in the rough. The fact that the SN shows it's a '99 is a good sign. The way the finish is worn off the headstock doesn't look like typical paint wear. I'm not sure what gold leaf wear looks like, but that could be it.
For 200€ it might be worth a gamble, I guess. I'm not really sure what the value of a clean RG-GOLD1 is...haven't seen one sell for a while. I'm guessing it might be in the US$2500+ range.
If it does turn out to be an RG-GOLD1 and you want to set it right, you'll have to track down a gold Lo-Pro, which might not be easy (or cheap)...maybe find one for 200€. The pickups will be another 100€+. That would put you in it say 600€. Gold leafing isn't particularly tricky (although I've never done it on a guitar), so that part should be within your grasp. Gold leaf itself doesn't come cheap, but 100€ worth should cover whatever is missing on that guitar.
Or, if you don't want to mess with it, if you can establish it's a legit RG-GOLD1, you can probably flip it in the condition it's in and make a decent buck.
Now, assume it doesn't turn out to be an RG-GOLD1. As long as it's not a complete Chinese clone, and assuming the neck isn't warped or otherwise ruined, the neck and body of a FujiGen RG are probably worth 200€. So you're covered as long as it's not completely worthless junk (which, based on the pics, seems like the least likely possibility).
Maybe go for it? <shrug> If you do jump on it, come back and let us know how it turns out.
