Three wooden Venetian blinds, these are over 20 years old but still in working order. I was struggling for photos showing them in place, you can see them behind our Christmas tree! They are big and heavy, car or trolley needed to collect.
Update: I just measured and dimensions are: All three have a drop of 185 plus cm, the smaller two are 69cm wide and the larger central one 116cm wide. So you can check the fit.
