If you ever encounter an old book or other bound thing that needs repair, here’s a reference to a guy that can do the repair. His name is Steve and he operates Special Bindings.
He is a a very pleasant guy and does good work. I have had a 19th century bible and an early 20th century prayer book repaired there. He can handle leather and cloth bindings, and he is careful to do repairs so as to make them very inconspicuous.
Here’s a link. His contact information is there.
