looking for key hadle for this model

Hey there. Looks like you have an 82-218 Mortise Lock. For a keyed handle set that works with this lock, see the 82-030A or 82-030B. The difference between these two handle sets concerns the placement of the thumb lever and key lock. The 82-030A has them perfectly centered between the mounting screws, while the 82-030B has them offset towards the lower screwhole. It's tough to tell what the case is with your handle set, so compare both with your old hardware and see what matches best.
