Also the arms on each window mechanism that opens and
Closes the windows are all cracked and broken. I'm not entirely sure what they are called. Could you help me find and order these parts.
Thanks for writing in! I'm sorry to say I would not be able to identify the awning window operator you need based on the patent number. Unfortunately, there are a few different operators that populate in our database when searching it. That said, I'll need to see a clear photo of the back of the operator, from a front profile view; it is important to see the placement of the installation holes. I'll also need to see a photo of the link arm.
In regard to the window lock on the side of the window, unfortunately, we would not be able to supply you with a replacement for the metal attachments. The plastic piece looks very similar to the 39-538 Nylon Cam Lock Pair, this is typically used along with the 39-537 Lock Assembly Pair. I would also suggest taking a look at the 39-539 Anderson Vent Hinge Pair.
