Top hinge, R hinged as viewed from exterior

Hello, I am looking to identify a replacement part for a Weathershield window from the early 2000's. The 3-hole stainless track is 10 inches long with an "L" stamp. The 2-bar hinge is 7 5/8 long with four holes and a "60" stamp. The other bar of the hinge is 5 7/16 long with a "6DN02" stamp. The slider broke off the hinge. I am looking to replace this hinge, but I also want to identify the original hardware manufacturer to have better info for future parts ordering. Apparently, Weathershield discontinued stocking parts for windows made before 2009. Thank you!
