Searching for Afg c754

A quick learner says:
I'm looking for a replacement latch for my sliding glass door. I have attached a picture of the latch that is in the door. The only marking I can see on the unit is etched into the window glass. It is AFG C754. Please let me know if you have any clues on what make/model of door this broken latch is for.

Thank you or posting. Please take a look at product 82-226. We believe your mortise latch looks similar to our latch and we would like for you to compare the two. Get back to us and let us know how that works out for you.
