Any pictures of the neck? Yes, this is a late "The Martin Tenor". Wurlitzer onwed "The Martin" and sold the the brand, and maybe the machines/tools? , to Leblanc, Kenosha, WI in 1971. It's always interesting to own a late sax from a legaendary model. No stencils were made and the kept the design/construction to the bitter end. Just a few details: The late "The Martin" have adjustable key bumpers. It was just on the Magna model. No adjustable right hand thumbrest. A small adjust screw (for the octave key) on the neck as well. These saxes were/are popular among "Rocksax" players. The Stratocastor and Marschall amp best friend! Still used by "pro" on the road. We are talking good quality!I think Joe Arnold (Stax, Otis Redding, Aretha Franklin, Albert King, Bobby Bland, Van Morrison ...) is on a late "The Martin". Good luck with your Martin. There are some guys in IA that are very good on old Martin saxes.
