English Heritage (EH) looks after around 400 guns and cannons at their sites across the country. Context Engineering carries out a programme of conservation and maintenance on the historic ordnance in conjunction with EH’s Collection Conservators. This work includes: 

• Inspection, condition reporting and surveys of ordnance requiring future full conservation;
• General preventative conservation and maintenance such as in situ cleaning, spot paint repairs on metal barrels and carriages and protective treatment of unpainted wooden carriages;
• More interventive treatments such as removal of cannon and carriages off-site for major repair and full re-painting;
• Making and fitting new wooden tompions, quoins and stool beds; and new metalwork, such as lynch and cotter pins;
• Roping down barrels to prevent tipping; and
• Moving guns and cannons for re-display.
