Part missing that attaches arm to window on window closing mechanism

Question

Thanks for your help.
The part that's missing is circled in red. It connects the arms that push and pull the window when turning the crank to the actual window.

There's engraving in one of the arms that says
14D307
PAT RE34657

The bottom right of the glass says
Trulite
tempered glass
CPSC CFR120-II
ANSI Z97 I-2009
W31 1/8 UA TP M
3914

Thanks for posting. This awning operator looks a little unusual to me at first glance. I'm forwarding this discussion to a senior colleague, and we'll get back to you as soon as we can with more insights. Many thanks for your patience.
