A bit of info about this odd machine...

It was called the Killen-Strait, I have no idea why it had such an odd name, so if anyone can enlighten us! Richard Hornsby and Sons produced it in June 1915 and is pictured here being tested in front of Churchill and David Lloyd George at Wormwood Scrubs. It successfully cut through barbed wire I believe.
After that trial they mounted an armoured body onto a Delannay-Belville chassis, but this proved unsuccessful and any further trials/production was abandoned.
I think this was Englands first foray into the world of armoured, tracked vehicles.
