After the war the UK army took over the panzer tank factory and I believe using some of the original German labour plus all the parts which were lying around built I believe 17 tanks.
Some of these were shipped to the UK and they were extensively tested by the RME.
The big problem they encountered was in the drive line which left much be be desired. The post war Leopard seemed to address the faults which is why so many are still in service.
