Lilac glass shade spare part for Jo Hammerborg Senior table lamp 1960s

Offered for sale as a spare part, this is the purple top-layer glass shade of a Senior table lamp designed by Jo Hammerborg and produced by Fog & Mørup in the 1960s. It is in excellent condition with two chips (see photos) – one to the central rim which is completely concealed by the cap when in situ on the lamp, and the second a flake chip to the outer rim measuring max 10mm x 6mm. There is also a tiny 1mm fleabite to the outer rim which proved too small to photograph. Please note that only the purple (lilac) glass shade is offered for sale, and the image of a deconstructed Senior and the vintage catalogue pic are only included for context.
