Currently putting together a list of surviving First World War Trophy guns and trench mortars that still survive in Britain, any chums help? To start with, here’s a 15cm gun buried at Esholt Hall, Bradford, discovered in 1980’s and now on display at Beamish Museum

Also aware of ones in Honing (Norfolk), Campbeltown, U-boat gun in Chepstow, Erwood, Millport (Isle of Cumbrae)

There used to be one in Hartlepool as part of a ‘bell buoy’ sculpture that was stolen in January 2018. But what’s that underneath the bell? A minenwerfer! Source - https://www.geograph.org.uk/photo/4745837
