Der Celac,

I've been to the Seitz factory and met the brothers. I'm sure they'll do very small runs -- Alpa isn't exactly a mass production item, and in fact, nothing they make is mass produced. Thomas and Ursula (owners of Alpa) are non-engineers, but the Seitz brothers translated quite vague ideas into gorgeous cameras. I'd certainly recommend that you contact them, but as I say, it won't be cheap.
