A bit of help needed to identify use and/or period
I'm a bit new to metal detecting and am working some old sites. This one is a house built in 1900, there may have been another dwelling on the land before that starting around 1750. This item is very heavy and I believe not that old - looks machined. Im just not sure what it would be used for and am thinking its from the 1950s or a bit earlier. I found it about five to six inches deep.
Could it have been used as a hoist of some kind? the end has a link that looks like it is a joiner. just guesses on my part. Any assistance will be appreciated.
