I don't believe your handle set and mortise are made anymore. We don't sell either, but we do sell a handle set that can replace the original: our 82-030. While the design is different this should still install comfortably on your door and work with the original hardware.

The mortise lock is unfortunately not something we can substitute. If yours is not broken then I highly recommend reusing it.
