I am missing the operator handle for an Eagle window. It appears to be 5/16 " . I thought I should check with you to be sure which Anderson part will suffice since it is an older window.

Looks like you have a Truth operator, which usually have an 11/32" spline. With that in mind, see our 39-107 cover and 39-114L handle.
