Treasure Found

I was asking Uncle Tito where I could buy food stuff which isn't Argentinean when he said he had some English Mustard of Colman. I thought surely not the same thing. He brought round the below, it came it a war time tin similar to the tate & lyle golden syrup and there is not made date still visible. There is only one thing left to do to make sure. If I blog tomorrow it didn't kill me. Wish me luck!
