|This collection of plans and drawings of the Commission's estate was kept and used by the Surveyor (Cluttons) until 2005 when it was handed over to the Commission's archive. The legal ownership of the collection is vested in the Commission, and it is therefore not a deposit or loan. The Surveyor has retained some Estate plans still in use and some have been disposed of. (Neither category listed here). The numbering of the plans is that used by the Surveyor.
