Years ago a friend from the UK gave me two Ely primed "O" bore punt gun cases. They were roughly 5 inches long and about 1 1/8 O. D. At the time he said they were valued at 75 pounds? He had built his own punt gun and had it proved at Bermingham. Hunted it once a year, the rest of the time he used his 8 bore Greener on ducks and geese. They still have fun in the UK!
