Steve Balfour has sent these in. The Units simulated appear to be Preston sectors 1, 2 and 3 and Hack Green. Feed sectors include Manchester Zone, Manchester Approach and Liverpool Approach and Antrobus. Hack Green was an upper air space unit (?) so was Antrobus still providing a lower airspace radar service or maybe a military feed sector?
Looking at the sector maps its interesting that there is no A25 Wallasey Brecon route but there is an airway between Stafford and Brecon running north of the old DG27 ADR from the GX to BCN. Might this be an airspace trial to develop a Daventry bypass route, pre PATCRU and JATCRU Lindholme. I’ve seen maps as late as 1957 with no A25 but with an Advisory Route from Stafford to BCN and the old DG27 connected with that route just about over Pershore.
