Parts found on wartime airfield, any ideas?

The Carbon type things could be off a searchlight , electrodes that give out the bright light ,

From a Hawker Hurricane Bruce?

Yup, thats what it looks like to me 🙂

Carbon arc lamps eh?, Thanks Nick:)

Oil tank cap I think

Circular item looks like a fuel filler cap – have seen something very similar on Hurricane crash sites – if the cap wasnt so corroded it would have the capacity in gallons engraved into it. The hook looks pretty general purpose, perhaps from a cargo lashing strap? Finally the carbon rods – found loads of these when I used to go bottle digging – they are the electrodes from carbon arc electric lamps.

I have found a few bits of this on this particular airfield in the past. It is very light and has a core rather like a thick version of pencil lead. Two sizes found, Nine sixteenths of an inch wide and seven sixteenths of an inch. They are not old batteries nor are they carbon. Found near a former dispersal area
