Rare guitar, Wilson mercury neck, custom Zemaitis styled shaped body. Very well made from one piece of mahogany. Trade mark aluminium control cavity cover. 
Lovely maple neck recently refretted with Dunlop 6100 Jumbo frets. Neck dates the guitar to circa 1976. The bridge is a unit found on the Shergold Meteor, and the Hayman Comet.
The bridge pickup has been rewound by Bare Knuckle pickups too their Nuntucket ( Leslie West !!) specs. Fab clarity, no mud, loads of attack and clean crunch.
The neck is a mini humbucker which has a superb jazz tone and mixes well. Machines are the nylon body Schaller types, also often found on Shergolds of the time, as is the zero fret.
If you are looking for something different! with obvious links to the great days of British made gear.
Reminds me also of a John Birch in some ways, esp the neck.
