Anderson window lock handle

A home owner from Maryland says:
I have 2 windows hopper style, each has 2 locks on each side of the window shown on pictures. Missing handles on both. I wonder if you could identify the part.
Thank you

I'm not sure if we have this exact style, since Andersen changes them every so often, but see our 39-291 lock handle and either the 38-285 or 39-290 lock bezels. Let me know what you think.
