Your not the only one phill, i'm in the process of developing a new yard as well.Isn't it amazing how much sh*t you seem to collect over the years. I've got some heavy gauge band and plates there that I bought some years ago, that are covered in what looks like tar. After some enquiries I found out that they had been used for the racking that held the crown jewels and valuable works of art in some caverns above a place called Blaenau ffestiniog in North Wales during the second world war.
