Identify a Gretsch

[Zillie]

Hi guys,
I'd like to find out what kind of Gretsch is this:

I guess it's a custom model or more likely customized (missing knobs) as Gretsch guitars don't come with P-90s

thanks in advance

Its a customized Gretsch 6120 with P90's and the bigsby bar is shoved underneath the tail bar.
