Vintage cases are the perfect compliment to an old side-by-side or double barrel
shotgun. Here a couple nice ones on Ebay right now.
Abercrombie and Fitch tooled leather gun case. Perfect for a Browning Superposed. This case looks like it was made for an O/U with 2 sets of barrels — maybe a Browning Superposed.
Winchester Leg O’Mutton for 2 sets of bbls. This is pretty hard case to find. It would be perfect for a M21, 2-bbl set.
