Awning window hardware identification

A home owner from Las Cruces, NM says:
We have these awning windows 58" X 34", interior wood (pine) exterior metal clad in a home built in 1999. The manufacturer is unknown to us. We may need new round knob crank hardware as well as screens and gaskets. Can you identify the product? I found no glazing stamp to go by.

Hello,

We'd be happy to help but we would need you to open the window to show us the arms of your operator that move the sash. This will help us confirm which knobs and handles would be compatible. 

Unfortunately, we do not carry replacement screens but you are welcome to look through our selection of replacement parts to repair them here

As for the gaskets that you mentioned, we would need to see an end profile of yours uninstalled, along with written-out dimensions, to compare to our inventory. Thank you.

Thanks for the quick reply, attached are the images requested. The manufacturer is Truth hardware. Do you know if they make a standard handle crank mechanism we can replace these knobs with?

Thanks for getting back to us. Your hand knob resembles the 39-115, which installs on an 11/32" diameter operator spline. If your spline is the same size, then you can also use a standard handle like the 39-114L. Take a look and see what you think.
