Hurd replacement crank

A home owner from Illinois says:
Dear Sirs

I have Hurd casement windows, the house is approx 10 years old, two of the windows crack out but do not crack back in.

The two windows are sized:
2. 45"/24"

Attached is a picture of the cracking mechanism

I am looking to order the parts necessary to fix this problem

Please advise

Thanks for posting, Donald. Please take a look at our 39-253R & 39-253L and compare their dimensions and style to your own hardware. Do you think these would work? If you aren't sure, please fully remove your operator from the window and take a few pictures of your operator. Please also provide the dimensions of your operators as well.
