1940s Casement window operator replacement

Question

Hi, could you help me find the right product to replace these with? I looked at the encore 39-449 and 39-450. Are those the correct ones, and what other pieces would I need?

Thank you!!

Thanks for reaching out!

I recommend taking a look at our 39-020 and 39-021. The compatible track is part 39-504. Double check the measurements to determine if these might be a better fit. Let us know what you think.
