Help identifying replacement window screen frame corners

There are no numbers or markings on the corners themselves. The frame has the this number on the sticker D-X71645.
Dimensions;
Length from corner to end of insert tip - 2 1/4"
Width of insert tip 5/16"
Depth of insert - 7/16"
The insert end has a tab that lines up and inserts into frame - the depth at the tab is - 9/16"
The corner has a small recess on the non-screen mount side to match the frame profile.
The screen mount side is open so that the screen can be installed in the corners.

Thank You in advance!

Thanks you very much Paul. I may try to keep looking for a bit since mine are white. If I still have no luck these may work. Thank you again for your response and information.
