old locks on patio and screen doors

Hello,

We'd be happy to look into this for you but we would need to confirm the distance between the center of the installation holes of both handle sets to compare to our inventory. Thank you. 

Your mortise latch appears to be a match to the 82-218. We do carry a handle set similar to yours, the 82-033, but the mounting holes are at 3-15/16" where yours looks like it is closer to 5". 

I could not find a handle with the same mounting holes as yours, so you would need to drill new holes to install something like the 82-030. Take a look at this assembly, along with the rest of the related parts and videos.
