This is CONN alto saxophone was purchased at an estate sale. Scratches and use wear, small 1/4” dent near the bottom. Marked N 86864 Mexico on back side. Under Conn the brass is worn and reads PROP CHGO BD ED so I assume this was a beginner student instrument in Chicago schools. I believe this Sax was manufactured in the 1970’s. I have no knowledge of instruments so I do not know anything about the operation of the instrument or how well it works. Selling as is with Pro TEC canvas case with hand and shoulder straps. . There is a receipt in the bag dated 2005 showing Sax rebuild (I assume it was this Sax). The exterior of the padded canvas case is dusty/dirty and needs cleaning, the hardware has some surface rust.
