The guns you mentioned are from my collection and are live pigeon guns .These are smaller in size and weight but not in bore size and should not be confused with the same gage fowlers.I have enclosed an image of big bore fowlers ,from top to bottom are 10,8,4. this does show the difference between both types of guns.
