Sounds to me that your gun may well be a 14G brass case gun. W Ford was a recognised specialist maker of "fowling/pigeon guns, in which category your gun may fall. If you measure (gauge) the barrels at 9" from breech this will confirm whether the gun is a true 14 gauge or if it was built as a thin brass case gun, in which case the barrels will be 12 bore... designated as 14/12. Thin brass case 12 bores had 12 bore chambers and 10 bore barrel... known as 12/10.
Hope this helps.
