Fionn,
I am from Australia, I recently came into possession of a piece of harness equipment from a pit pony harness circa 1890 - 1940.
I was actually fortunate to be at the original stables underground at a mine in Australia when the piece was given to me for identification. The piece in question is shaped like a man's boot, it appears to have sweat stains on one side and wear marks on the other. My thoughts are that it was used on some part of the harness to prevent chaffing of the pony.
As an underground miner and a horseperson I am intrigued to learn what this is.
I sincerely hope you or some one reading his page may know what this is or have access to some one who could help.
Yours from down under,
Shane Reid |
