I started on a Conn NW I stencil, and having gone back and forth, find I prefer the vintage tables in general. The difficult transition from C# to Bb and back is often easier on the very old horns: Martin Handcrafts, Conn NW II, Buescher TruTone. I don't like the more modern Buescher horn G# table - as on the 400 - that high pitch does feel like a typewriter and works against a compact, relaxed hand for me. I say go vintage, especially if he already loves the horn. If weight is an issue, older Zephyrs are lighter than Martins and some Bueschers by a bit, and great players.
