The 82-081 is the complete handle set and includes installation fasteners. The mortise lock and striker are just sold separately. Let me know if that helps!
It was my pleasure. If you have any future hardware questions, you know where to find us!
I'm afraid we haven't heard back from the home owner from Edwardsville Ill if the parts we recommended worked for them or not. With that said, our 82-080 and 82-081 are the best options we have for the hardware pictured in this discussion thread. Compare our dimensions to yours to see if they match up to your original handle.
Great! Best of luck with the repair; we look forward to hearing how everything works out!
