Project Information

Hall Conservation Ltd was asked to undertake a survey and conservation specification for the Royal Artillery Collection housed at Windsor Castle. This project is due to run for five years and started in the summer of 2011 with the conservation of the sixteen 3 pounder field guns, made by Kinman & King c.1790-1800 and sited at the lower battlements of the Round Tower.

The work involved removing all of the failed paint and corrosion from the cast iron gun carriages using mechanical methods, but the very first stage of working on any guns is to ensure that it is not loaded. Cleaning and stripping failed paint was followed by the re-painting of the carriages with a modern paint system of proven durability. The bronze barrels were carefully cleaned by hand and given a protective wax coating to protect the bronze from the elements. In addition to the cleaning and repainting Hall Conservation Ltd also designed and fitted tompions, a plug for the muzzle of a weapon to keep out dust and moisture.

Due to the location and weight of the guns, logistics and budget demanded that the work should be carried out in situ. The weather was particularly unkind at the time and rigging weatherproof workspace on historic structures without installing fixings to the fabric of the building is a challenge.
