Bay window left and right crank operator's identification

A quick learner from Yarmouth maine says:
Hoping you can help me identify this operator for a bay window probably from the 1970s. There's no part number on any of the hardware except for an eagle on the tip of the handle. The arm length is about 12 inches long with a plastic roller on the end. I need two of these.

Hey there!

Our 39-014 looks similar. For a new handle, see the 39-114L or 39-205 depending on your preference. Review the specifications and see if they match up with your old assembly.
