The gun was almost certainly a 12 bore chambered gun. Most British guns of this era were underbored although usually one sees 13 or 13/1 on the proof marks. I can't make out the letters in the diamond among the proof marks. Does it read "12 C" inside the diamond? (see the indispensable W.W.Greener, "The Gun and its Development" for bore sizings, etc.) 14 is a bit tight but imagine your barrels again like most have been bored out a few times to get the spotless bores you mention.
Black accraglas makes a dandy substitute for "ebony" (it was likely horn in there originally) if you are handy. You might even be able to make a satifactory repair to your butt plate with it as well.
