I have a Higham 12 bore side by side with spare fully choked barrels.. I’ve owned the gun for over 30 years.. the story I have is Purdy made the barrels and Holland and Holland made the action, which were sold under the table, the gun was then put together by Higham. I’ve owed a Purdy and know H&H guns well so I believe this is highly likely.. can anyone shed any light?
