Operators and hinges are bad. Appear to be straight arm (windows are rusted shut).

Thanks for posting. Take a look at our 39-264 Andersen Split Arm Crank. You will want to remove your old operator from your window so you can carefully compare all the dimensions to make sure they match. If you need a new hinge, see our 36-048.
