I have a silver plated Conn jazz trombone. Played in HS '95 and '96. From the serial number 41-347915 it appears to have been made in 1991. I'm unable to figure out the model number of this instrument. The bell measures just under 8" (7-7/8"), is engraved in cursive with "C G Conn Ltd" and there's a 483 stamp on the slide piece. Ultimately, I'd like to sell this instrument because it hasn't been played and it should have a proper home. Before I sell it, I'd like to know the model number and approximate value. Slide is in fantastic shape too. Any help is appreciated.
Thank you
