Here is a video of the creation of this bell: https://youtube.com/shorts/YpKnzQpq3os?feature=share

Kindly read the description in its entirety if you're interested:

Copper plated olds bell. All un-lacquered. Does not come with tuning slide. Consider that you might have to remove some of the copper from the threads, depending on how your slide fits (though it fits on my olds recording fine). There are various inconsistencies and marks from past dents across the bell. *Also be aware that you will have to do some alignment to make sure your tuning slide fits this bell.** All these things a technician would be aware of, of course! The bell is fairly straight, but not perfectly so. It bends a bit from the main brace (see photos).
