Help with a Caradco wood casement window

I have a vintage awning type window from of course Cradco, wood casement type, I believe.
I am trying to open the window to let hot air escape from the kitchen, hadn't been opened for two + years. The California heat is on its way 90+ for a week. Anyway I digress, the plastic high density glider broke on one side, so I want to remove the window itself, take measurements of the bracket & see if I can find a metal replacement. When I open the window completely & slide the bracket in the the horizontal position does the plastic brackets come out horizontally with the window? A two person job. Photos later.
