This is a complete window which was salvaged from a 1952 Elcar vintage trailer. I do not believe it is an actual Hehr brand window but it is built like the Hehr window so that is why we call it a Hehr style. The window frame, window jamb and interior trim are all aluminum but the window braces, window arms and window hinge are steel and therefore rusted. The steel hinge on this window is froze up from rust. It may be able to be freed up with WD-40 or PB Blaster but no guarantees. This window does come with the interior window trim. The glass is good but the seals are old and should be replaced. There are no screens but they were just flat screen that were pinched between 1/2" wide alum trim around the edges so they would be easy to duplicate. The actual rough opening for this window is 12" x 30-1/4".
