broken casement window operator

Question

I have a broken casement window operator.  The only ID on the window is stamped on the sill track & is R 902 WC.  This is an egress window and the dimensions are greater than the operator I've seen on this site.  Photos follow -  Thanks in advance if you can be of help.

Hello, thank you for posting,

It appears that your window uses Pella hardware. Please review the style and dimensions of the 39-175 operator. Compare to your original to confirm a good fit! If you need a new handle, see the 39-109B, but note that the original cover will need to be reused as it has been discontinued.

Let us know if you have any additional questions.
