Smith Gun - Cheap and cheerful British artillery

At the Imperial War Museum they have an example of a Smith Gun. This was a cheap artillery weapon issued to Home Guard units.

Using a 3 inch smooth bore barrel, it was designed to fire standard 3 inch mortar shells. Though it was claimed to have a range of 1500 metres, in practice it was found to only have a range of 450 metres.

Warlord Games is releasing a model as part of their Operation Sealion range.
