Those were never Koch Media titles. Wasn’t this just a reissue of some releases from another German company and Koch Media is only the distributor not producer of this box set ?
By the way I don’t think the Koch Media release of Sartana Kills Them All were English friendly bit that is also ancient. All real Koch Media releases from the last 10 years has been English-friendly. They are in a spaghetti western league of their own.
