is that an early model then, it certainly looks different to most of the eggles i am familiar with
I believe so.
It was made at a time either when Eggle was trading under the name of Climaxe Guitars, or it was a very early model from when he just started up as P.E. Guitars, used as a Fore runner to the Berlin.
There's a story around that Paul Reed Smith approached Eggle at a Music Show and asked him to redesign the body and headstock shapes as he felt they were too close to his own designs. This may be why the Berlin looks different?
I dunno how much of what I just said is true, but that's about as much info as I've been able to dig up so far :)
