Recovered Vikings
I think you will find that there are now plenty of 'recovered' (ex SS) Vikings back at Syerston or en route, so why is the 'system' not using them.
Probably because they threw the baby out with the bathwater in their haste to reorganise a system that did not need it.
The 'schools' operated despite the lack of a capable 'Head Office'; when the schools went so did the capability, and rebuilding is a huge task.
