Daryl, The name on the Hunter drawing for the forend lug is Loop, and the short rib between the barrel lug and the loop is called the Loop Stem. There are two or more designs for the stem, with a much heavier design being used on the Long Range or Wild Fowl versions. I have seen the same heavier type stem used on some other guns with a splinter type forend, usually on trap type guns. I am not sure what is gained by the use of the heavier type stem, as it is only soft soldered to the barrels and the loop. Also the loop is only soft soldered to the barrels, which is why it sometimes comes loose as in this case. The loop and forend iron are closely fitted as this is what controls the fit between the forend iron and the frame. Otherwise the pressure of the J spring will cause friction and wear between the frame and the iron.
