HC Deb 03 August 1909 vol 8 c1696
Mr. MIDDLEMORE

asked what was the value of Simpson armour as compared to Era, Krupp cemented, and Harvey-Nickel steel?

Mr. McKENNA

As no actual firing trials have yet—so far as the Admiralty is aware—been carried out on Simpson armour, it is not possible to make any statement as to its value. The question of actually testing a Simpson plate is now under the consideration of the Admiralty.
