Again, thanks for all the help guys.
A friend at work is into Guitar restoration/building and is going to have a look at it for me after X-mas. New bridge, frets and nut and another re-wire.
The quality of the wood doesn't seem that bad, I'm not expert so don't know what it is. It is quite heavy - as is the Franconia LP copy.
As said it really has got a lovely tone.
