Radiator lockshield valve (Stobhill NE61)

One of our 24 year old radiator valves has started leaking due to a broken internal part. It appears to have a 10mm inlet pipe and a 1/2” connection to the radiator. This old size is no longer easily available, so I’m looking for someone doing a refit of their kitchen (or bathroom?) who might be throwing one out, probably still attached to an old radiator, possibly in a skip, ideally in or near Morpeth.
