Need a crank operator for Anderson window

Hi there, I can't find the right crank operator for my Anderson window. Above see some pictures. The picture of the crank operator installed is for the window on the opposite side, opening in the opposite direction. I did not include the installed mechanism on the window in question because my contractor disassembled it. However, if you have these crank operators, I'd like to get one for each window, opening in opposite directions.

I found various numbers on the mechanism. On the back there is 59400 8A, with a B underneath it. On the back of the articulating arm is the letter C and further to the sidde of that is 1 09 05

Underneath those numbers at the bottom of the articulating arm is the number 1484
On the other side of the crank operator is the number C-9400A1 with the numeral 7 underneath it.

The width of the mechanism, not including the articulating arm, is approimately 7 3/16 inches. The articulatin garm is about 4 1/4 inches. The height of the mechanism is approimately 2 3/4''.

I hope you can find me my required part(s). As I mentioned, I would like to replace the mechanism on both windows. I don't know if the numbers on the mechanism on my other window are exactly the same as it has not been disassembled. It's the same window but it opens in the oppositie direction. Thank you for your help. Please, please, please try to find the part, as I can't open my window without it.

Can you show me pictures of the part you are recommending, tell me the dimensions of it, the price, and how to order it? Also, what is your return policy if it happens not to fit my needs. Thank you.

Thank you for your response.
Can you explain how that part can be used for both windows that open to the left and to the right.
Also, what is your return policy, if this is not the right part.

Thank you very much.

I am so sorry. I can't find your prior response with the link to the page to order the part. Could you please send it to me again? Thank you. Kathleen
