Is my rear Trillium window salvageable?
Before I continue cleaning the awful mess of wood, caulk, glue, dirt and heaven knows what else was left behind when I pulled out the window A/C unit, I need to know if the window is even useable. It looks like a P-PO actually hacked off some of the frame when he removed the emergency hatch to put in the A/C. There are screw holes and missing frame "lips." I really wanted another jalousie but was just going to settle for a fixed window somehow, but I'm not sure I can even do that.
If it's ruined, can anybody suggest an alternative? I really don't want to lose the remaining jalousie, so if someone has an idea what to do with the hole, I would be so, so happy!
Here are some shots of the exterior and interior. Hopefully the hack job is visible. I'm not sure what it's supposed to look like, but I don't think this is it:
