I wish them luck...the market for a low A alto is extremely rare. The only reason the low A was ever put on the alto was because when Marcel Mule was a developer for Selmer Paris, Marcel had specially requested it put on the Mark VI, which he helped engineer a lot of btw (for all you jazz die-hards

). I'm not sure whether Marcel had run across the low A in classical literature and had either forced him to play a normal A, or if he had some sort of contraption built into his SBA horns, but either way, that's why it's there.
It might sell for a bit, as considered a "cool" horn, but the fad will fade and the producer might be left with little to show for it.
