Have you called Bausch & Lomb? Even if they no longer work on scopes, they might be able to refer you to someone. You might also google "rifle scope repair" and see what comes up. There is probably fungus growing in your scope, and it will be rather costly to repair. Don't be surprised if nobody wants to fool with it, or will demand a healthy deposit just to get started.
Rich or poor, it pays to have money.
