The Northolt/Abingdon MK22 PK624 is indeed with TFC at Duxford and was stripped down for restoration a few years ago, but I don't think has progressed much as the major effort is focused on the P-51C, Beaufighter and Sea Fury.
Northolt then had Mk XVI TE476 which is the aeroplane restored by Tony Bianchi for Kermit Weekes and now flies from Polk City.
The Uxbridge Mk XVI was RW382 which went to David Tallichet. It was destroyed in a fatal accident in the US in 1998.
