The other Nav kit consisted of one ADF, one TACAN, the Doppler fed Ground Position Indicator and the original Nav Bombing System fed from the WW2 era H2s Radar.
The H2S that was included in the NBS the V-Bombers was H2S Mk9, it 1st saw light of day in the mid 50's.
I helped the guys from EMI install the 1st RAF NBS set up, it was included in the 'Trainer' that was installed at BCBS Lindholme in 1954-5.
It was very different from the H2S Mk 4A that we had fitted to the Lincolns at the time.
