Found this company accidentally today watching some video demos from Danny Sapko on YouTube, who owns a few of them. They're a UK company and they offer 30-1/2" and 32" lefty basses in Telecaster and Stratocaster designs (as well as a Rickenbacker/Telecaster hybrid). All of the lefties are out of stock right now, but it looks like they're built to order. Given the low price points, I assume they're made in China (though he says he assembles them in the UK, so no idea what the quality is), but they sound pretty great in the demos:
