WWI Officers Private Purchase ‘The Lifeguard’ Pocket Trench Periscope by F Duerr & Sons of Manchester. 22553:6. WWI Officers Private Purchase ‘The Lifeguard’ Pocket Trench Periscope by F Duerr & Sons of Manchester. 22553:6. Antique & Militaria

A 'Lifeguard' 1915 Patent Periscope made by F.Duerr & Sons, Manchester. These were privately purchased by officers to be used as trench periscopes with the threat of enemy snipers ever present. This left-hand model is the earlier type of Lifeguard with no supporting 'U' pieces at various points. The Lifeguard was introduced in early 1915 and then upgraded as per the second model to give more rigidity. The dark patch on the mirrors is age-related deterioration of the silvering. This example has the 'Lifeguard Patent Duerr' motif to both mirror plates with only the postal initials 'S.W.' which is distinctly WW1 period manufacture only. Undamaged mirrors with hinged action working perfectly *some aged related tarnishing*. Sadly, missing its carrying pouch, these are now becoming harder to find. The price includes UK delivery. 22553:6.
