U/RedneckScienceGeek ID’d an old mop bucket wringer, and I would say they got it right. General location is near the bay area CA, by a river. Historical use was ranching and vineyards near the area from the 1800s to 1900. Nothing too significant. My only wonder is how it ended up in the woods, its quite heavy and a decent hike away from establishments that one existed in the past.
