Here are some closer photos.
Raimey. Yes both rifle barrels have the crown over G proof and are rifled.
Just behind the forend hanger there is another mark not shown on the original photos.
Mike. The questionable crown over V shows better on the enlarged photos. I wonder if it might the mark for guns "in stock" when the proof law of 1891 went into effect.
I plan to do a chamber cast tomorrow but a .393" gauge pin fits well in the bore.
