to the window it may have been mortised
I don't see any screws so I guess it is mortised (which I hope means glued).
They are made by American Craftsman, thru Anderson, bought at Home Depot. Guy there said to call them because the part is free. Lady on the phone said I needed a receipt from 8 years ago

OR the number on the tiny paper on the window that has obviously been faded or I washed off.

She was not impressed with my description of the broken piece and "can't send me a replacement without the correct numbers".
I found the company name on the piece (

4)Hhe says it was glued in the first place so it should be able to just be re-glued. He says high end apoxy would be what you want, should be about $15 cdn. Follow the directions on the glue exactly, you should be able to just hold it in place until the glue sets (he figures 5-10 minutes), but then you wouldn't want to use the window for the rest of the day while it all cures.
Thank Wes for me.

I just KNOW it can be glued because I am so freaking stubborn, I will just glue it anyway. What is "$15 cdn" in American words? Is that the price?
