I had a 1917 Conn bari I picked at a used typewriter shop for $50 when I was 19 (45 years ago). It had "USN" etched below the serial number - obviously a navy horn.I used it as a second horn to march with in college band. It was sort of a pea shooter compared to my relatively new SDA bari. I sold it several years after I graduated for a couple hundred bucks. I'd love to have that horn now. The foolishness of youth.
