Replacement Handle

I am trying to replace the handle and lock on my Cole Sewell Estate series storm door. It is a keyless locking dead bolt that you only lock from the inside. The outside is a handle and a 9" decorative piece of metal with a screw on the top and bottom. It came in gold years ago, but it is broke so we need to replace it and would like other color options. I know this is a long shot, but thought I would try.

These are pictures of the handle that needs replaced. If there is something available, we would like it in oil rubbed bronze, but are open to other options. Thank you.
