Truth casement window replacement parts

A quick learner from Massachusetts says:

Hello!

Can you please help ID the parts used in this casement window measuring 22.5" w x 38" h?

The hinges are Truth brand, so I assume the operator is the same. The operator case is cracked and won't open the window anymore.

Do I need to replace just the operator? Or do I need to replace the operator and top and bottom hinges?

This is for left and right side casement windows over a sink in the kitchen.

Images attached for left side.

Thank you!

Lawrence

Hi there!

Start with taking a look at our 39-014 and 39-013 operators. Review our dimensions and compare them to your current operator to see if this could be what you need.
