Gear box for window crank

A handy person from Sidney,Ohio says:
I am looking for a gear box for my window crank. The windows are made by Therma Gard. The gear has the name Truth on it with the numbers 30710 and 40254. The gear box sits on the window seal. The window has a vertical hinge on the left side as you are looking out the window. I have lived in the house for 10 years, so the windows are older then 10 years.
Thanks K. Doak

Good morning! Thank you for contacting our discussion board. Have you seen our 39-031 & 39-032 EntryGard Dual Arm Operators? These appear to be similar to your own hardware. Make sure to match up their dimensions with your operators.
