The Crank system is Entrygard truth, there is a number of 40941-A but that number is different on all the windows
The windows are Marvin but I can't find any identifying numbers other then the glass information.
The house was built around 1999-2000, so I'm assuming the windows are some kind of Ultimate Casement
I would like to change out the crank to a fold down so it doesn't interfere with the shade operation
Thanks
Linda
