Crank ID

A quick learner from Detroit says:
Good Morning,

I have a home in Detroit that was built in 1949 that has all metal casement windows. The cranks are all non operational and I'm looking to have them replaced. Can you match these?

Sure, I think we can find something to replace this. I'll need a bit more information to start out, though. If possible, I would like to see this operator out of the window. One of the most important details is the arm that physically pushes and pulls the window when you crank it, and seeing your operator removed will let me look over this arm. In the meantime, you can look through our selection of replacement casement operators. You may be able to find a good match there.
