Old Screen Door Corner Bracket

I am in need of a new corner bracket of this style for my old sliding screen door. The bracket has an adjustment screw that tilts the wheel up and down, while the wheel pivots on a hook on the bracket.
Unfortunately, I cannot locate any brand or part number from either this part or the door. The rectangular profile of the bracket that slides into each side of the door frame is 1.5" wide by 3/8" thick.
