I have a window crank with id numbers:

1 361 405L on the 14 inch arm

And on the bottom:
f-9400-8A

I need one replacement. What part number do I order from you?

Dave Sr. from SWISCO responded:
Please take a look at our 39-331 operator. This is used by Andersen on their newer windows. You might also need to purchase the sill adapter, 39-362, but only if your window was manufactured between 1995 and 1998.
