POW operator #JWO-1

A home owner from USA says:
We are missing the right side operator of a double alum. awning window (4 stack).
Here are two photos: first one is close up of the operator we removed from left side of the double window.
second one is another window in the house showing the RIGHT side operator that we want to find.

You can see that the handle is on the bottom of ours and yours is on the top. However, the window store that identified the operator for us as POW JWO-1 says the manufacturers frequently put the handle in different places for different windows and that your operator should work if we turn it over.
Should order 39-182 or 39-183?????

Thanks a million!!!! I'm so glad to finally find this thing!

I believe our 39-182 and 39-183 are the only choices for this old POW window operator. See what you think. Before installing a new operator, I suggest lubricating the linkage in the window with a type of silicone spray, then operating the window by hand to make sure there is nothing hindering the operation of the window. That could potentially be the only problem.
