Pulling back brambles and scraping ground and found this, approx 6 feet by 3. Thought was an old tank but lifted the lid and it's only about 1.5feet deep with a mechanism in it.
Thinking some sort of weighing scales but don't see how get the weight as only 4 little holes on each corner, possibly for lifting lid? And there was no sign of how you'd keep an animal on it, and its away from the old sheds. And why underground rather than a platform one or just at the mart ?
There's been no work done on this farm since the 1940s so it's definitely older than that.
