1920s Alto Saxophone, Vintage Conn/Pan American Pertin Paris, Gold/Silver Over Brass

Vintage Conn/Pan American Saxophone.  It has the stencil 'Pertin Paris' on the front of the bell and is also stamped with the ID Ptd. Sept. 14, 1915, followed by 1153489, A, P32321, L  (photo included).  This serial number unfortunately does not offer an accurate creation date, since it was likely made specific for a direct store.  However, I was recently informed that its manufacturing year is most likely 1927.  If any collectors out there have any other ideas or information, please feel free to message me, (this has been a fun lesson on Conn instrument history.)  Based on research of other similar saxophone's, it does look very similar to Conn's New Wonder II model of the 1920's, but I am not certain of this.  The finish looks to be gold and silver plated brass and is in pretty good condition for its age.  It also does feature the mother of pearl finger inlays, but not the inlays on the rollers.  There are scratches and worn areas.  The instrument needs a good cleaning and new pads.  I can not speak for its sound, it has not been played in my presence. 

The sax will come with a case (interior in excellent condition, but outside has many dings) and the other items pictured.    Thanks for looking!
