BRITISH MILITARY CTS TRIPOD WITH EXTENDABLE LEGS

This is a British Military Tripod with extendable legs, this has a Broad Arrow stamp on the mount, this is made from steel, this stands at Approx. 30' tall before releasing the legs, the hole on the mount measures 5cm diameter, there is also a CTS stamp on it for Cooke Troughton & Sons London so I reckon this Tripod is for some sought of Optics.
