For a photo of some Scunny ladles in use
http://murrayliston.fotopic.net/p31991652.html
Colour scheme looks basically bright rust,with white stains on ladle and general black gunk over the chassis
Just ahead of #34 in photo is a ladle laid on the ground showing the bright rust interior.
The ladles are no longer used but a few examples are preserved around Scunthorpe.
