Weighted base for IKEA desk lamp (Thrupp, Stroud)

Now slightly regretting having given away our heavy weighted desk lamp base we had in the 90s/00s.

It’s flat metal with a slight depression in the middle, for storing paper clips etc.

Does anyone have one please? A flat weighted base with a hole in the side for the desk lamp-end to be sited in.

Thank you,

Helen Bell, Stroud.
