My h.s. band had three 2350s and two H.N. White souzys - one was the "Giant" model with the larger bore and tall pistons and the other was the 1250. All silverplated.
I think the 2350s had a *slightly* more 'hollow' sound in comparison to the 1250.
The "Giant" was in it's own league with it's very deep, large sound. But all played and sounded great
