snap-in window edging / glazing

need assistance in finding edging that matches or is similar to what's installed.  home was built circa 2007 and this edging is weatherd and needs replacing.  It does not appear that it serves anyting other than a decrative purpose, beyond keeping the edge clear of debrie.  Measurements are aprox owing to age of item and using a ruler -- length is ~ 13/16" with width ~ 11/32".   Have attached pictures of edge view, top view and underside.  Color is bronze to a brownish, however as this is located on the side of home just about any dark color would likely be sufficent.  My thanks in advance
