The Martin Baritone #204XXX
This is a rather rare bird. It had been a one-owner bari that had been custom ordered from Martin in 1957.
It came into the shop in need of restoration, and was bought by a local pro bari player who had us do a full custom overhaul on it.
These are the after pics.
Finish: Original silver plate on body; nickel plated keywork; gold plated bell interior
