This is a rare instrument on the used market. It is similar to the Wessex Festivo, but this is basically a Willson 2900 configured in the American style. This one has been modified with a large-shank receiver to make your mouthpiece shopping a bit easier! And it has a main tuning slide trigger, which I assume was added; at least, I don't recall it being standard equipment. The included hard case has wheels added at the bell end for easier toting (the Willsons are very heavy instruments). Condition of horn and case is excellent. The bidding starts at $5,499 (ordering a new one will cost you over $10k) and there is a Make-Offer button.
