Casement window operator

I need a new operator/hinge for a casement window. The hinge/arm fallout of the window bracket whenever it is opened to the point where the opening to connect the hinge is.

Ive looked through your website and don't see a match for current operator. It says it is a Truth hinge with the number 30744.

I would appreciate any assistance in determining a replacement product.

Thanks. Mike

Thanks Tom, The 13.5" appears to be the correct operator. Much appreciated.
