4 (Dec 2011) The corrosion of lead plumb bob was first noted in the summer of 2011. The item was later assessed in December 2011 and the deterioration was the same, hence this object is assumed to be relatively stable. This object will be observed again in a few months' time and additional precautionary measures may be taken (suggestion of placing the item in a small plastic box with a plastazote lining and silica gel crystals). Ideally, this object should be stored in the long term in a drier environment.
- Acquisition date
- Acquisition notes
- The Ilbert Collection of clocks, prints and other related material was destined to be sold at Christie's auction house on 6th-7th November 1958. As a result of the generous donation of funds by Gilbert Edgar CBE the sale was cancelled and the material purchased privately from the beneficiaries of the Ilbert Estate.
Ilbert's watches were then acquired with further funds from Gilbert Edgar CBE, public donations and government funds. These were then registered in the series 1958,1201.
