casement window operator

Question

I have wooden casement windows and need to replace some of the operators. I have attached pictures of what I have (they are either 9 1/2 inch or 9 3/4 inch arms I think). They are original to the house and are from the early 1970's. I have not been able to locate this exact match and would like your help in identifying it or a suitable replacement.

Thank you for your time and help with this.

Hello! I have also come across your type of operator in other discussions. I suggest looking at our 39-027E along with the related parts to see if you could adapt this operator to your window. Your hardware is very old, so there is no guarantee this will work.
