The plan appears to come from the same source as MP/DOV0390. Various room labels and a key which were on this plan have been scratched off; leaving a faint, but readable, mark. the plans of the wall passage and chapel have been circled in pencil and labelled "omit".
The plan is undated, but is in the style of the Ministry of Works plans and has a Ministry of Works number, so has been given their dates.
