I need to replace crank handle for old Patriot casement windows. Looks like the bore measures 3/8-inch, and the width of the handle is 3 inches There is a number "13" on the crank handle and it attaches to the operator NO. 30866. The color is taupe, but not too concerned if doesn't match

39-104 would probably work well as a replacement for this handle. The 3/8" bore is the most important detail.
