Lockmaster Multipoint Lock Gearbox - 45mm Backset, Latch & Deadbolt
Read "Lockmaster 304" on the face of your lock and look at the center of the strip. If it throws a deadbolt, this gearbox replaces the case behind your handle; the hook version is a separate gearbox. Lockmaster is Yale's multipoint lock range.
The gearbox has no spring of its own, so your handle set must have a spring cassette or the levers will droop. It is non-handed: undo the screw in the latch, take the latch out, turn it over, put it back and refit the screw.
