Marvin screen door lock

A home owner from USA says:
To Whom It May Concern:

I am looking for a specific part to replace for my parent's house's sliding screen door. The screen door lock is broken, however many people have told me that the Marvin screen door is hard to replace, so I am trying to locate a place that can just sell me the locking part. I took apart the part and it reads the following:

(I also need the little silver bracket piece. That seems to be the locking mechanism.)

Thanks for posting! You say you need a screen door lock, but your pictures show the handle for the sliding glass patio door. Do you have the screen door handle on hand we can see?

Thank you for getting back to me. Please kindly see attached pictures of where this handle is actually installed onto a screen door. I have also included a close up picture of the metal locking mechanism.

Ah, I see. This is very odd! I guess they used a patio glass door handle as a screen door handle. I'm afraid the company that made it is no longer in business, though. I think our 82-008 lock set should match, but you would have to re-use that locking tooth in the third image. Is that a possibility?
