Truth awning window operator

A contractor from Annapolis Maryland says:
I need a replacement for this hardware piece but want to confirm the correct one. Mine measures 24-3/4" from one arm end to the end of the other.
My best guess is your "Sill Mounted Awning Operator
Product Code: 39-348"

Please advise,

On the bottom of my operator is Truth 45142 see photo

I agree, the 39-348 looks close. Make sure to measure from the center of the hole at the end of each arm, I think you'll find that's closer to 24".
