Replacement handle lock
I'm afraid I cannot identify what you have from these photos. Without the original hardware it will be very hard to identify what you need. I also cannot make out what your measurements are; your tape measure is at an angle in these shots and I cannot determine what sizes you need.
If possible, please tell me the exact hole spacing (center to center) between the two outer installation holes for both the handle and mortise lock. If you also happen to know the brand of the door, that would be a huge help.
I can't promise that we can get you the hardware you need without the old hardware as reference, but we will definitely do our best.
