It's only what was said at the time. Maybe they had a regular production and a dx production run and colored them accordingly. A lot of the earlier machining wasn't always that exact on stock corsas so we'd notice big differences in the finished products, and regularly have to take one cluster off and replace it. Some were so bad it was difficult to adjust the derailleurs, others so smooth they felt like silk and were so quiet it brought a smile to one's face In our opinion consistency was far better and constant on the oros, but as you mentioned it deteriorated towards the end of the run. Again, the quality control on washers varied so we had to regularly added or delete same to get good bearing adjustment. Ahhh- The pleasures of not worshipping at the font of mediocrity. Ted Ernst
