'All CV-4004s are "select" premium tubes, with low noise and long life properties. CV 4004 types have various plate structures and "halo getter" sizes'

Huh ? Where did you see this ? Mullard CV4004 is not specifically a 'select' or 'low noise' type . The data does state that it is a reliable type though . It has unique construction compared to other ECC83 and is a ruggedised version (as are all CV4xxx devices) . Plate style stayed the same throughout production with the best sounding examples being made in the early 1960's

Never mind the hearsay , here's the spec sheet...
