2 pounder AT fired on wheels

[centurion]

Searching for something completely different I cam across a photo of a 2 pounder in the field being fired from its wheels. I'd always believed that this gun had to be used with the wheels off and the four legs folded out. Either a leg was being used as a trail or there was actually a wheeled conventional carriage for this weapon. Does any one know of a 2 pounder equipment like this?
