David Zagar Double Ring Model 6*.
Original condition, measures an exact 95 on my gauge.
Comes in the original tube with his test data sheets.
A superb  player very consistent with Otto Link Double rings. It is dark and lush and smooth with a fat core and easy response. 
When Mr Zagar was in business he was selling these for $700 USD so this is a tremendous savings and the piece is in excellent condition
