hi called a searchlite sax / by martin sax brand if thinking of selling contact me please

That horn is a Martin Committee I, otherwise known as a "skyline" or "searchlight' horn. The serial number makes it a 1937 horn.

That example is a beauty. It's straight and shows very little lacquer wear. Best of all, there's nothing distracting from the bell design, which I think is one of the coolest ever. Pure art-deco exhuberance, America moving to take the future by the tail under the steady guidance of FDR, aided by airplanes and tall buildings sweeping the skies with searchlights! Martin afficionados are going to drool.

The case is a Conn case, not original to the horn.  The pads look newish.  There's a slight bit of moisture discoloration in the shot of the lower stack key.  The pads are plain pads without resonators, so they're not a real selling point.

I used to play an early Martin Indiana, which had the same body design but with not as nice keywork. It was a sweet and pure sounding horn, with a slightly dark aspect.  It also blew really nicely.

Like most earlier horns, the keywork might seem clunky to someone used to modern horns.  But either someone wants a Martin or they don't.
