Corner piece next to screen frame

Do you have that metal, corner piece? This is a 1960s aluminum awning window, typical Florida type. The one on the left fell off and my dog destroyed it. I had to tape over the holes.



It looks like you might be talking about a hole cap for an awning window. These holes are typically where the operator installs, but if the windows aren't functional then a cap is installed in the same spot for appearance's sake.
The bad news is that we don't sell any cap that matches the one you show on the right side. This is a very old window and in all likelihood the part you need no longer exists.
We do sell a generic cap, our 39-355. It's only made in white plastic and while it's very versatile, it's by no means universal. Still, it is our best and only option. Look it over and see if you think it's usable in your case.
