It could be Artec. I know the guy behind a brand of acoustic guitars who sells 200.000 guitars wordwide a year. They make 'm on his order with his brand name in four different Asian factories. He orders all the hardware for a year in once, so he can ask very high discounts. He asked me what a 250 euro Fishman pick up (that's the price if you buy it in a store to install in you guitar) costs. I thought like 30 euros. It's five! And Fishman still makes profit!
So maybe artec sells to big companies very cheap too.
