Identify these windows/doors I have these old windows. I am unsure if they are even official lego.
LEGO logo is visible inside hollow studs on genuine parts. While it is hard to identify if pictured items are genuine LEGO parts, such elements have been produced as LEGO:

Window 1 x 6 x 3 Panorama with Glass



Window 1 x 3 x 2 could be either one of these.

Door 1 x 2 x 3 Hinge on Left



Window 1 x 1 x 2 could be in two versions: with integrated glass (single piece) or with glass that can be attached (two pieces together).
