Marvin crank upgrade

We have quite a few Marvin windows and we'd like to replace them with folding handles. I have taken a few pictures, but have no idea of the model and didn't want to completely disassemble the hardware. Is it possible to tell from these pictures if the Truth Folding Handle and Cover kit (39-107FK) will be a match?

If you have Truth brand operators then the 39-107FK should fit, especially since you have center-oriented splines. Open your window and see if the "Truth" name is on the operator arm. That should tell you.

It is a Truth operating arm.
