Pinson Bomb - replica
Date of manufacture:
This replica was made within the Department of Anaesthetics, Cardiff under the direction of the Chief Technician, E. K (Ken) Hillard.
The Pinson Bomb was designed to be filled with ether, sealed, immersed in hot water for a period and then used while still hot. Pure ether vapor emerging would be fed to the anaesthetic breathing system where it would be diluted. The heavy cast, gun metal construction, necessitated by its pressure vessel status, also provided thermal inertia to support extended ether vaporisation.
