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.
