The one thing that that there is plenty of and a common sight scattered around farms is rusting farm machinery. Farmers never sell it because it may 'come in' or be used as a donor to repair other usable kit but this item seems to be beyond the stage of redemption by being used for donor parts.
I was out one morning walking Lucie, our single Parson Jack Russell Terrier, when we came across this mysterious and somewhat strange rusting skeleton. Could we work out what it was? No. The farmer came along and he couldn't remember what it was but we were told it's 'old though' and he'd put it there just yesterday.
Never mind there's nothing like a mystery object and it's simply being left to just gently rust away.
