David: I have two guns with two sets of barrels, and both have two forends. One gun is a 2E grade with a straight stock that was originally built in 1906 with two sets of steel barrels. The other gun is a Pigeon grade, originally built in 1909 with a HOT, ejectors and chain Damascus barrels. It was sent back to Hunter in 1927 for a second set of steel barrels. Both sets of barrels have their own forends.
