Michael you are right I do want an old 6 bore mold. It is for a Jover & Son, London FL rifle, quite splendid. 10.5 lbs.,27.5" octagon, .815" groove, 9 grooves, gold lined waterproof pan, etc. Wm. Jover went bankrupt 1796 and this must have been made near the end. Bought it at 1999 JCDevine sale of Lanny Samaon collection. Samaon was a physician and a member of the tony NY Arms and Armour (note spelling!) club. He was driving across one of the Hudson bridges when there was an accident. He stopped got out of his car to help and promptly had a heart attack. I am quite proud to have his rifle.
