Thanks Lynda, Adds to my knowledge as well as reinforcing some that I knew. Gunter's chain is a name I have never heard of. Must Google. Gunter's chain is 22 yds or 4 poles; as he says standard. The current sandard - at least pre-metric. Cheshire having had a 32 yd Chain and therefore an 8 yd or or 24 feet Pole. I wonder who had the 15 feet, 18 feet and 21 feet Poles :-) :-) :-) Regards Neil
