No 3 Periscope Mark 1 : Captain R L Leane, C Company, 11 Battalion, AIF

Battle damaged metal trench periscope. A Turkish bullet penetrated the top aperture damaging the glass insert. The exterior of the trench periscope has several dings from use in the trenches. The remnants of a rectangular shaped piece paper are stuck on the upper rear of the periscope. On the side of the periscope is hand written in pencil 'Captain R L Leane O.C. C Coy 11th Regt 3rd Brigade'.

During the Gallipoli campaign Australian and New Zealand troops used both specially made and improvised trench periscopes to observe Turkish and German movements in their trenches.

This is an example of a battle damaged specifically built British No.3 Mk1 periscope, a type that was commonly issued to Australian and New Zealand Company Commanders on the Gallipoli campaign.

This particular example suffered a well aimed bullet strike from a Turkish sniper on 28 June 1915 when it was used as part of a 'demonstration in from of Pine Ridge trenches'. The demonstration was made to prevent Turkish reinforcements moving south to where the British were attacking. The 11th Battalion AIF suffered heavy casualties during this action, with all Officers killed. The donor, one of the famous Leane brothers of the AIF, Raymond Lionel Leane, was himself slightly wounded.
