Max Poilu Posted 13 March , 2006 Share Posted 13 March , 2006 Like much war material these were made by various companies to standard patterns. These folding wooden box type periscopes were officially designated the No.9 from 1915. MkI's were made by Adams and R.J. Beck - a name commonly seen on the brass two piece periscope (MK no. escapes me at the moment - got one in storage somewhere!). They both look like MkII's - 'Trenchscope' had the patent for this originally, it's an improved model with a hidden glass screen as well as a shutter. Have you got the base spike Bill? - these are usually missing. Lots more info in Saunders 'Dominating the Enemy' - along with the first book in this series essential reading for any 14-18 militaria enthusiasts.

MartinWills Posted 13 March , 2006 Share Posted 13 March , 2006 one is marked Adams, the other Trenchscope. It is interesting that some of the manufacturers of Trench Periscopes were companies normally in other lines of business. One, apparently, survives today manufacturing marmalade!

6th Hauraki KIA KAHA Posted 22 March , 2008 Share Posted 22 March , 2008 Hi I thought i would add to this thread, with this info from one of my signals manuals and a pic of my 1917 Mark 11 as in Manual The Periscope is carried in a brown canvas bag provided with a fastening buckle and web sling for carrying. There is a pocket inside the case containing two spare mirrors. The periscope itself is made of light wood and is rectangular in shape measuring when extended, 2 feet 1 1/2 inches, and 1 foot 3/4 inch when folded in case. it is kept in the folded position and a patent catch to hold it rigid when in the extended position At the bottom of the instrument is placed a steel bar fastened by means of a clamping screw, at the other extremity of which is fastened a steel pin 12 inches long and 1 inch wide, which can be clamped in any desired position by means of a thumb screw. Two mirrors are placed in position one at the bottom facing the observer, and the other at the top facing in the direction to be observed. These are placed at such an angle that any object coming within the field of the top mirror is reflected into the mirror at the bottom. A piece of thick glass with half an inch of surface exposed is placed perpendicularly in front of the bottom edge of the lower mirror. Unless telescope or binoculars are being used with the periscope' all the observations are made by looking through the piece of thick clear glass on to the mirror. The remainder of the aperture is closed by means of a sliding metal door, which should only be kept open when observations are being made by other means than with the naked eye.
