Thanks for reaching out! May I see a photo of the existing hardware. I'm sorry to say I cannot identify the replacement match based on the brand.

I'll need to see a photo of the operator base and its arms to confirm the correct part.

Please let me know if you have any questions.

Hi. Thanks for the reply. The label on the window, made by Silverline, states: series 3150 casement, P.L. # 352-006. Please see attached pics to see if they are a help. Thanks

Based on the photos, it looks like you have the 39-317 Truth Split-Arm Operator. To confirm that this is the correct replacement match, carefully compare the dimensions below.

The opposite versions is the 39-318. The compatible hardware and accessories for both can be found tagged below.
