I've taken three up-close photos of the broken part which I've included with this message.
Unfortunately I did not take a center-to-center measurement between the mounting screws, but can do that if needed. Just let me know.
The red arrows indicate the part that's broken and needs replacing = essentially the handle to grab it by.
Btw, it's really not necessary that the gripping/locking mechanism works, though I think it still does.
The red oval is the point where the original handle broke off at some point in the distant past before I owned this property.
