I am an happy owner of a baritone JP 373 Sterling lacquer, bought used about four years ago. Apart the initial problems of intonation ( it was flat across the board and I cut all the slides), the instrument is solid, sounds good and well built. As far as lacquering is concerned, I can say that it leaves a lot to be desired: if seen from close up there are points, the most difficult to reach, with a coarse finish and, in the places where the hands rest, this has been consumed. Anyway it's a nice horn for the price. I highly recommend it.
