No.16 Hants 83.7.15

This is a WD-only version of Hants 83.7.15.

Much of its interest lies in what the surveyors were not allowed to survey. The Convict Prison, top-left is OK, though we are denied interiors - the chapel looks particularly interesting. North of this is the Dockyard Railway, which ends at a level-crossing gate: what it does east of that gate is secret. The road continues north of the railway - this part was deleted from the sales edition - and there is a grand entrance with a control office to one side. Beyond the office is a patch of lawn with a tree, and then the security blanket descends. To penetrate that blanket just a little we need to return to the 1:2500, (1), where in the grey ink we have already seen being used for Dockyard Extension, we see four 'Docks'. As for the basins we saw earlier, the detail is quite skeletal, though if we want more detail we can fast-forward to the 1930s when secrecy was dropped and even the sales edition was allowed to show what went on behind the dockyard walls - https://maps.nls.uk/view/105989344

So is this detail skeletal because construction was in progress when the 'grey-ink survey' was done, or was the local Ordnance office trying to piece together a picture of what was happening behind those walls from contract drawings and such other sources as it could gain sight of?
