| Hi F'light
That sounds like a horn that I sold to Marek in NYC a year or so ago.
Tuning bell trumpets have certain advantages and disadvantages, but I always like having one around (currently a terrific Spada C that belonged to Balazs Nemes -- principal trumpet of the Frankfurt Radio Orchestra and a wonderful player).
Treat it well for at least 3 hours per day :)
Best,
