While out wandering one day I stumbled across a metallic object. It was rusty at its lower end but other than that it appeared unremarkable. Later I discovered that there was something unusual about it. Something written on it (C119) is anomalous, and so to mark that I've attached a cache to it. There's no need to go to the given co-ordinates, they are for a busy junction and the cache isn't there.
Identify these eight pictures and together they will show you the way to the cache. Once you've done that (and made use of the hint of course) you can use this checker as confirmation.
