Flapping Madly
Not having knowledge of Roll's supply chain or what they may still make internally, it is hard to say exactly who made this stub tube component. As I suggested in a previous post, there are companies today that produce these components. An example would be Parker Hannifin, an American company with a worldwide presence. From their web site, you can see the various array items they produce, either of their own design or to the customer's design and specifications. Also, they produce tubing of all sorts including stainless steel and nickel alloys. I would bet however, this part is sourced out and not produced internally at Rolls Royce. But I could be wrong.
