HC Deb 14 December 1922 vol 159 c3171W

asked the Under-Secretary of State for War the calibre and extreme range of the latest French heavy gun, and the number of those guns now constructed or in course of construction?

Lieut.-Colonel GUINNESS

The latest such gun in use is believed to be the 305 millimetre (railway mounting) gun, with a range of 31,000 metres. I am not in a position to reply to the remainder of the question.
