SWISCO - The Replacement Hardware Authority

Unknown sliding glass door missing hardware - please help!

A quick learner from Roseville, CA says:
I am a homeowner in Roseville, CA. I recently moved into a house that has a sliding glass door that is missing the handle, latch mechanism, and the part that the latch hooks into. The screen door is also missing hardware. I have been to several local sliding glass door shops, but cannot find any hardware that will fit the existing holes in my door. The only markings on the door that I can find are on the glass itself (it says 'herculite' in the corner of the glass). Other windows in the house are marked with "GA" on the window latches, but I'm not sure if the sliding glass door is the same brand. I have provided pictures of the door with a tape measure next to the existing holes in hopes that you can help me find the appropriate parts. As can be seen from the first picture below, there has been one additional hole that someone drilled at the bottom of the other holes. The door seems to originally have had 4 holes plus the big oval hole in the center. If there is anything you can do to help, I would greatly appreciate it!

Concerning the glass door rail, it looks like you have screw holes at about 4" apart. The door looks like it is solid with no mortise inside latch, so I believe you need something like our 82-261C outside mounted handle. Look it over and see what you think. If possible, I'd like the distance between the screen door handle screw holes.

Thank you. Unfortunately, your dimensions are not familiar to us. We are having a lot of trouble finding something that may work. It's especially hard without seeing the old hardware. If possible, we would like to see some photos of the edge of the screen door, as well as the patio glass door. I would also would like to see the keepers which the screen and glass door locks latch onto, if you still have it. Finally, are there any labels or tags anywhere on the main frame of the door or track? These could help us identify the door. Please let me know!
