Hi, I was curious about the different bell colors on Bach 42 Stradivarius. From what I`ve seen, I understand that Bach doesn`t make "rose" bell trombones, but I could be wrong. However, I`ve seen pictures of trombones with "Bach 42G" stamped on the bell and they look more like "rose" instead of gold. I`m just wondering if the gold-brass bell on Baches is suppose to look reddish or what?
