Could you please let me know if you have this part available. I believe it is a 3/8" reverse flange

Yes, this looks like a reverse flange corner key alright. I would suggest looking at our 95-246. This might be our best match, but it would require you to cut out the inside part of the corner. That way you could reinstall the screen back into the frame. The screen cloth should cover up that space on the inside of the corner.
