If it says Conn on the bell, it's a Conn model 90G valve trombone. It was their answer to the trombonium. It is made from an 8H/88H bell section mated to a 0.547" bore valve section. Most of them that I have seen were purchased used in marching bands. I own one already, although mine has a small patch on the leadpipe. I have seen these selling on ebay for between $300 and $500.
