Hello,

This is a very old handle set, which I don't believe is available. The good news is, I think you could get a surface-mounted handle like our 82-033 to work if you redrill the installation holes to match the 3-15/16" hole spacing. Look over the part and related video to see what you think.

If you need to replace the mortise lock as well, please open the door and show us the clock to compare to our inventory. Thank you!
