The awning window operator has number 30897 stamped on the arms. I believe it to be Truth 30897 or 11.14. The color is bronze. It is a double pull operator and has window attachment points 9 inches apart. The arms are 25 inches long in the closed position.

Take a look at SWISCO product code 39-015. This operator sounds like what you are describing and yes, it is a Truth window operator with a bronze color option available.
