Modified Trolley Accumulator
A trolley accumulator was designed to contain a series of batteries that provided an external, ground-based source of electric power (with a variety of voltages available) for an aircraft. It was typically used to start-up aircraft whose internal batteries were at best only marginally capable of the job.
Seen in the RAF Museum at Hendon, this particular hand-pulled example from the 1940s has been modified with a small petrol engine fitted on top to provide power for recharging the batteries.
I find it interesting that the RAF doesn't seem to have been able to find a set of matching tyres for this exhibit...
