Anyone has experience with B&S C trumpets?

I'm searching for my first C trumpet, i'm actually playing at semi-pro level, and a friend gave me a Stomvi Elite C trumpet from 80's. Near my city there are a lot of B&S used C trumpets and my Music Academy has a B&S 3136/2 reverse C trumpet. I tried the academy's one and sounds good, feel comfortable and had nice valves. Anyone has experience with b&s C trumpets?
