Keep it,Cool find.But don't tell my wife where you found it.We were searching a 1890s narrow gage track and on the way out she kept falling behind.Going up a steep hill i had to push her up it.I couldn't figure out why she was having so much trouble till we got to the top.The back pack she was carrying was full of old rail road spikes.About 50 LB. worth.So if it is just ONE keep it lol...Osage
