A Complete set of Sash windows from a house down the road which was being modernised.
I actually asked if hey were replacing the windows and If they were could I have the old ones ?
They said yes, so I actually went down and removed the sashes intact from the windows when they were ready to fit the new ones.
Saved them Skip volume, saved risking them getting damaged 😀
They were float glass, same as My house (Which has a different refractive index to modern glass therefore the light coming through is different) so I then removed all the replacement (Modern) panes of glass that had been put in over the years, and replaced with the rescued Float Glass.
The whole front of the house now has matching “Flawed / wobbly” glass in it and is much the better for it 8)
I`m sure my Ex appreciates it just as much as I did 😕
