"The Martin Alto - Magna". (On Consignment - Plays rough, needs adjustment or rebuild).
It plays solid enough right now on the older pads to get a vibe of its powerful tone. Original finish with original neck. It is a later serial number, so the engraving script font changed, but all the other key components are there. This may be at the very end of the Martin Magnas due to the serial number. It actually required me to do some researching to get a rough dating.
Some research led to #305k being 1967; so we will be that year or later. Magnas are basically the same sax design as the earlier "The Martin Alto" or Committee III. There were a few key changes; LH roller add, the 3D silver cross on the bell and neck, and the more prominent nickel keywork.
Conn 1970s case currently paired with it. MORE PHOTOS & Sound File at WorldwideSax. This item is in the category "Musical Instruments & Gear\Wind & Woodwind\Band & Orchestral\Saxophones". The seller is "worldwidesaxonline" and is located in this country: US. This item can be shipped worldwide.
