awning window operator, possibly Look-Rusco

A quick learner from Jacksonville Florida says:
dimension of bolt pattern to window frame 5-1/4 inches on center.
width between screws top and bottom 7/16 inches on center (4 in all 2 bottom 2 top).
overall length of link arm 3-1/4 inches (hole to hole 2-9/16).
diameter of hole at end of link arm 3/8 inches, link arm is offset.
need new operator and also shoulder screw to attach link arm to window linkage.
could be a look-rusco operator no markings at all on operator.
Thank You, Richard

Thank you for posting, Richard.

We have researched multiple awning operators and it still appears the Swisco 39-257B Look-Rusco Window Crank is the closest match available.

I know the hole at the end of the arm is 5/16" (to your 3/8"), but it is the closest we could find.

Take a look and see what you think.
