replacement crank and latch for casement window

A home owner from USA says:
Good afternoon,

Thank you in advance for your assistance. I need a replacement crank and a window latch for a casement window. Here is some additional information:

Multipoint lock with 4 latches
Window measures 71.5" x 32"
Window opens right
Latch opening is 4 3/8" x ½"
depth to track connector is 1 2/8"
the diameter of the knob the crank attaches to is 9/32"

Thanks for your help,

I do not have the original parts at all, as the window was pre owned.

Hello,

We'd be happy to help but we would need you to open the window and show us the arms of the operator shown in your last photo that move the sash to compare to our inventory. 

Unfortunately, we have no way of knowing which lock would work for your casement window without seeing the original assembly. With that being said, you are welcome to look through our selection of casement window locks here. We apologize for the inconvenience.
