"Trolleyacc" on the wreck of the Thistlegorm (Red Sea)

The Thistlegorm was what made me take up diving in the first place and I’ve since dived it almost 20 times.
You’ve got a great selection of photos but the one referred to in as a trailer above has what I believe to be an incorrect caption (since changed) that has been made by a number of authors / divers.
The subject is not a trailer in the normal sense – it is far too small to carry anything worthwhile and the wheels / tyres are nothing like those on the trucks i.e. suitable for dessert use.
I have a photo taken at the RAF Museum before my last visit to the Thistlegorm of what was known as a ‘trolleyacc’ a battery or accumulator used to start aircraft engines.
The connecting cable in both our photos is identical.
I hope that you find this information useful.
