This is a Selmer K-Modified 24B from 1954 in excellent condition. There is evidence that it has been restored at some point. It has a .458" bore.
There is some very, very minor wear at the bottom of the 2nd and 3rd valves. It does not effect the compression or how amazing the valves move! There was also some lacquer that was touched up near the bell rim.
This is a great player and not one to miss!
