Kindermann Tank Dates

I recently bought a 34 oz. Kindermann tank. It has the stainless steel body and black plastic top. It came with two 36 exp. 35mm reels and a 120 reel, all Kindermann. All of it looks unused. The box is marked Made In Germany. Some of my other Kindermann boxes are marked Made In West Germany. Was the West Germany marking discontinued after 1989?
