Home Radiators (London Rd, HW HP11)

Hi Freeglers,
I am installing a heat pump and need to replace all my radiators.
So am offering up the old ones here. They need 1.5cm (fairly standard) diameter pipework. White.
Most are single depth (K1) but a few are double (K2) as shown on photo.
Width varies from about 80cm to about 1.3 metres. Standard height.
