I think it has come up behind the bridge. I could be wrong but it looks to me as if the saddle slopes down slightly towards the fret board. Behind the saddle there is a slight but noticible gap between 2 peices of wood - or is it a split? I can't see it the other side of the bridge. The back of the belly seems slightly arched up.

I am Jon Freeman, and yes we have met. I am in North Norfolk. John Hullah could (if he undertook repairs - not sure if he did) have been a candidate in this area but he retired due to arthritis.
