Old Florida Jalousie Window Handles

A quick learner says:
I am looking for the crank/handle to open my jalousie windows. My home in Florida was built in 1941. I assume the windows are from that era. There is no brand name listed on them that I can find. Please let me know what part I may need.

The handle that will work will depend on the size of your spline. You can learn this by measuring the diameter of the handle stem you show in your photo. There are many options, such as our 3/8" diameter spline 39-104 or 39-108, or the smaller 5/16" spline like the 39-274.
A quick learner says:
Hi Dave. Thanks for the quick reply! I'm not sure what it is you suggest to measure. If it's the very tip that measurement is 1/4". If it's the length of the stem then it's 5/8". I've included pictures of my measurements. Which do I use?

You would measure the total diameter. We don't have anything in 1/4". I would double check to make sure. The measurements can get pretty specific. The examples I gave are 3/8" and 5/16".
