crank mechanism on a jalousie window

A quick learner from HAiti says:
I hope you can help.

I sent you the picture of the crank mechanism on a jalousie window I am looking to replace.
It is for a house in Haiti. The house was built 15 years ago. The house jalousie windows pretty much all over.
I would need at least 10 mechanism

Thanks for posting, Myriam. I'm not sure exactly what you have without more detailed dimensions. Check out our 39-017, 39-058, 39-074, and 39-520 to start. Carefully compare them to your hardware and let me know how they compare.
