They did not develop anything. They are selling the same model they produced as partworks around a decade ago. They just added some extra frames and changed them to oak.There's no way a company is going to develope an entire kit and then sell only 700 of them. Maybe if there was some factor like a mold would only survive 700 castings or something l like that. A hard limit to what they could produce. But I don't see anything like that with this kit.
