I am a "day late and a dollar short" with this reply. I feel I must caution against paying a premium price for a gun just because it has two barrels and represented as an original "Utility" gun. These sets had two barrels with a fitted forearm for each barrel and the assembly numbers on both barrels should match the receiver and stock (under butt plate) numbers. If the numbers don't match, that is a good indication that a barrel has just been added at some point in time. If there is only one forearm and the numbers match, then one forearm could have been lost over the years.
