Venetian blinds (Odd Down)

Black, aluminium venetian blinds x 3, width 83cm x 1m 65 max drop. Having had some windows replaced and plasterwork done, these no longer fit. About 20 years old, still in decent condition and in working order, but one has a few not very noticeable slightly misshapen slats at one end. I washed them all when removed, thinking they would go back up. Also the simple fixings and screws. Definitely usable, it would be a pity to take them to the tip!
