The Dennis ‘Ace’ was purchased new from Dennis Bros of Guildford in August 1938 by the British Paper Company, owners of Frogmore Mill at that time. The Ace is thought to have replaced a Horse Drawn Shand-Mason Steam Pump which had been purchased by the Mill in 1913. The Ace has had a full engine rebuild in the past two years.

The Dennis Large Trailer Pump was obtained new by John Dickinson’s Apsley Mill Fire Brigade in 1938. The Trailer Pump was re-discovered and rescued by the PTHFB in 2009. It has subsequently undergone a complete overhaul plus re-spray and pumps as well as it did in 1938.
