Thank you chef 8489,
I totally agree that many instruments designated today as student or intermediate instruments made by the great makers such as Conn Olds and King were nothing of the kind but were very high quality instruments beyond the capabilities of most players.
And the King 2055T is one of those as you quite rightly say.
I would be proud to own a 2055T or S, and the OP's niece has made a great choice in selecting that instrument.
