casement crank from Truth

A quick learner from new Canaan Ct says:
I have this crank from 2002. It sits on the sill. I have two in opposite directions.

I have attched a photo. I believe this is a LH Maxim Dual Arm Operator, Sill Mount

Do you think it matches?

It looks like you have the 39-253L Maxim operator. Take a look at it online and compare the 39-253L product image to your actual operator.
