Looking for handles that would fit Swisco Multi-Point Mortise Lock with Pocket Plate, 12" (82-260)

Thanks for posting. The 82-260 is compatible with different kinds of handles. It's not recommended to identify your handle set based on the mortise lock for this reason. If you were to show me a picture of your existing handle set, we could recommend the best match.
