I have a different viewpoint on what this is.

Not sure what it started life as – drop tank or whatever, but surely if you are towing this behind something, you would’t want the drag of that handling ring.

No – I think this is a cobbled together training aid for the troops to pick up and run with – anyone ex British Forces / RAF out there done the ‘stretcher run’ with several full jerry cans on it, or the pine-pole run ?
