Need help identifying these casement window parts

I need to replace all the hardware on several casement windows in my home and i need help identifying the parts i should order.

Can you please help me identify which parts i should order based on these photos?

If you look at my order history, you can see the parts i already ordered so im hoping you can just validate that i ordered the correct parts.

Also, i need help finding the window latch that's in the photo image3. Its the hardware piece that locks the window closed.

I believe i need these parts:

1) 39-253RB/lb encore dual arm operator (right and left)

2) 39-375/6 truth folding handle

3) 39-529 truth hardware track slider

4) 39-528 1/2" casement track

5) ??? - window lock mechanism

Is that all the parts I need to replace all the hardware? Waht else do i need to order to ensure i can repalce all the exisiting hardware that has rusted on broken.

Thanks!

Great this is very helpful. I need help to identify a few more parts for my casement windows:

1) the track that the window slides on that sits at the base of the window up against the corner. Mine are 14" long and have a track that the shoe that sits on the bottom corner of the window slides in (see pictures). There is one of these tracks on the top and the bottom of the window to enable the window to slide open and closed.

2) I also would like to replace the shoe itself that slides along the track described above and attaches to the top and bottom of the window and slides into the tracks.

In the pictures, you can see the track at the bottom underneath the actuator. It's shiny silver. You can also see the show that attaches to the window and slides along the track.
