HC Deb 24 May 1916 vol 82 c2096
12. Sir A. MARKHAM

asked the Under-Secretary of State for War whether he is aware of the shortage of periscope pattern No. 14 at the front, and that in particular artillery observers have been unable to obtain this pattern, though they have many times applied for the same; and will he say who is responsible for this shortage?

Mr. TENNANT

I am informed by the Ministry of Munitions that every effort is being made to meet demands of No. 14 periscope, but, as these are complicated instruments, the output is slow. At least four other types of artillery observation magnifying periscopes have been approved to supplement the output of No. 14 periscope. These, while not being quite so good as the No. 14, are useful substitutes, and are being produced as rapidly as possible.
