a Parker research letter may show you if the gun was originally 2 3/4, Or a call to Doug Turnbull's shop may let you know if it was opened there They may also have records of what was done to the barrels- most importantly - was any metal removed to clean up the bores. But I seriously doubt a gun left his shop dressed up with no place to go - (safe to shoot) so the question would be has it been altered since the restoration.
My opinion is that the most important thing to know is the wall thickness. Many of these gun had plenty of meat in them to start - and a light cleaning out did those no harm.
these old guns - when in safe condition - are a blast (pun intended) to shoot. I shot a DH damascus over my dogs several times this season.
where are you located? we might be able to find a shop near you with the knowledge to check them.
