Unknown Awning Operator

Hello! I have about 8 awning windows that were installed new about 10 years ago so not too old. The location is on the Jersey shore so sand is always an issue with the gears which I'll be cleaning and lubing (silicon spray) on a regular basis going forward based on your site's recommendations.

I'm having difficulty identifying the correct operators to order. I can't find any ID tags anywhere so I'm not sure of manufacturer and model though maybe the attached pictures will clue you right in. I included dimensions on the key areas and should be accurate to within 1/16 or so. Color is white though I'll paint and add a white handle if a white operator replacement is not available. Once I know which replacement part is correct I'll order a few LH and RH replacements.

Fingers crossed you can tell me the necessary awning operator replacement.
