Hi . . . I have a vintage tenor saxophone made by Lyon Healy Couturier. Below the Couturier it says Chicago USA and has a number on it down near the bottom of it 11152 with an L below that. I have read many discussions on this site. It seems they made all or most Lyon Healy with Chicago USA before 1928 or so. Nevertheless, the number on mine is not as high a number as the ones I have read in discussions. Does anyone know what this is?
