Black metal curtain pole (University Area RG1)

This is a black metal curtain pole with curly end bits. It fits a single window not a full size window. I used it for my single lounge window. Each pole is 66cm/26" size and the smaller one (6mm diameter) slides into the bigger one (11mm diameter) so can be adjusted to size. I have the 3 curtain holder parts with the original screws. I gave the holder parts a good wash but there are still faint traces of paint on them.
