Cant find right hand window Operator

A quick learner from New York says:
This is from a house that was build in 1925. The arm that comes out of the box does not protrude out of the box when fully close which makes it difficult to identify the correct window operator. From what I could measure, the arm that is connected by the screw is about 2 3/8 in length.The space between the two bottom hole is about 1 3/16 and the top to bottom height is about 5 1/4.

Hi there!

We don't carry this exact operator but take a look at our 39-193 & 39-194, along with the other operators I have listed for you on this page. They have a similar hole pattern and link arm style, but look over the dimensions for each and see if any match your original hardware.
