Bathroom Window Crank needs Replaced

A quick learner from New York, USA says:
Hello,

We are trying to find the correct replacement for this window crank mechanism. There are four screw holes in the metal plate part, the horizontal distance between the screws is 3 and 7/8 inches. The long arm is somewhere around 7 and 1/2 inches and the shorter arm is in the 3-4 inch range. I didn't measure the longest back arm. The longest back arm attaches to the window using two slots.

Please let me know if you need more information - we're dying to find the right part!

You have an older style Andersen awning operator which is no longer available. Andersen suggests using the modern 39-206 as an alternative. Take a look at its specs to see what you think. Note that this is not a 1:1 replacement; you will likely need to do some adapting to your window.
