I am trying to find how heavy my 3.9kg cylinder was before being filled. I understand that it is stamped on the metal collar around the tap. However my metal collar is split into four quadrants, two opposite ones are stamped 12 12 a third is stamped 15/ 02. How do I know if it is 12lb 12oz or 15 lb 2 oz? In calculating the weight of gas left it makes a big difference. I would be grateful if somebody could enlighten me??
