An impressive item of Great War Zeppelin wreckage

An impressive item of Great War Zeppelin wreckage, being a large piece of rivetted aluminium framework forming a bracket with reinforced apertures for a cable or stay, one side endorsed in pencil "Brought Down in Essex by ... Sowby Sept 1916", and the other side in paint "ZEPPELIN. L. 33", 24 x 20 x 18 cm.

The pencil note on the side of the relic disagrees with the painted identification, because it refers to the Billericay airship, whereas L.33 was the Little Wigborough airship.
