This is a full F/Bflat with F.E.Olds and son Califonia on the bell.It is good condition for its age about 12 years old .The owner had it relaquered about 3 years ago and since then it has only sustained one small ding on the curve.The rotary valves are string and there is slight wear on the valve keys which is to be to be expected. It is the same horn so I have been told that F.E.Olds are making the same now as their current proffesional model the FH 581-1.It comes in a Reynolds case which has some numbers on it.The sound matches is strong and but not to wide as to be expected from an american horn.
