Throw A Spanner In The Works Traditional Cache

I was heading up the river towards Moorook when something caught my eye so had to do a Uturn and have a look. it was something that you don't see everyday so I decided to stick a cache out by it. it is a good excuse to get out and stretch the legs while on your journey along the Sturt Highway. The object the cache was named after is no longer there but this is what was there originally.

Good Luck
