Does anyone have any ideas what this is?
It was dug up on a former CW test area in the UK and had a liquid fill.
The picture isn't great, but it's approx 200mm in length and 80mm in diameter.
The end which looks like an ogive is threaded (the round disk is an id number and not related to the item).
The other end has what looks like a fuze well but no threads.
There's no markings on it either!
