A slightly abstract view of that well known 'heritage' colour Norfolk Bog Door Blue, the colour in this instance is on a guard cover shielding the chain drive on a conveyor belt. It does look good though contrasting with the rusty corrugated iron and the white highlight.
The conveyor hasn't been used for years and although it's a mechanised implement it is from a different age in farming so, now, it's just another piece of farming equipment that has become redundant because of the march of time.
We've said before that Norfolk and probably most of England must have tons of scrap metal in the form of agricultural machinery just lying around wasting away.
