Thanks for posting. At first glance, this looks like the 39-171 Dyad Operator. Please compare with the dimensions below and let me know if anything differs. For a handle that works with this mechanism, see the 39-114L sold separately. For a hinge set, see if the 10" 36-048 matches what you have. Let me know if you have further questions.






The exact size of the operator body shouldn't matter much. The style has changed a bit with the newer replacements, but with rare exception it will fit the original space just fine. More importantly is the dimensions of the split-arm. Let me know if those differ from what's listed below in any way. If it doesn't then you should be good to go.
