Thanks for reaching out to us! The hardware you have pictured here resembles the 82-056 Andersen Lock Bolt Assembly. The compatible thumb latch is the 82-049 Andersen Thumb Latch. I would also suggest taking a look at the 82-048 Andersen Latch Mechanism.

All of these products are made for an Andersen PermaShield 3 panel sliding patio glass door.

To confirm if any of these would be a fit, carefully look over the dimensions and compare them to your existing hardware.
