I have a couple that I have thought about repairing but I have not moved forward. The only thing that I can think of, is maybe contacting a Strop maker and see what they have to say about either repairing the strop or making a new one. As for the razor itself I have no idea as SE razors and I really don’t get on.
Hello, some are glued, others are not. Anyhow, the inside of the case is nickel plated brass, so removing the glue (it most likely became already brittle) is no problem. There are two little tabs at the short end of the hone/strop, pry these gently up and remove the plates.
