Help needed to identify shell casing

[Guest]

Hi All, I work for a museum service in the UK and we are in the process of trying to identify a number of items and this is one of them. Unfortunately military related ephemera is not the focus of the collection, and therefore I have been carrying out some internet research, and after coming across this forum I was really hoping that someone might be able to help us out please.

Unfortunately we don't have much to go on at the moment apart from it was likely made in a local munitions factory called Kryn and Lahy in Letchworth Garden City. Possibly during WW1 (or WW2)

It measures: Height: 10 inches (25cm) / Diameter of top: 2.36 inches (6cm) / Diameter of base: 2.95 inches (7.5)

The copper band is 0.59 inches (1.5cm)

We would really appreciate any general information about it, but a confirmation on whether it is in fact a shell at all would be very useful.

Please let me know if you need any additional information, and thanks again.
