You can also find a significant weight range with Foxes which you will not find with Trojans. Fox had 4 different barrel weights, varying significantly from lightest to heaviest. With the Trojans, within each gauge (12-16-20, same as Fox offered), all guns were supposedly built on the same frame: 12ga, #2, 16ga, #1; 20ga, #0. (Seems I recall a few exceptions, but not many.) Thus, all 16ga Trojans, for example, will weigh pretty close to the same thing--varying mostly with barrel length. In contrast, you can find 16ga Sterlingworths with the same length barrels varying at least a pound in weight.
