1892 "Trapper" question|Winchester Rifles|Forum|Winchester Collector

Back in Dec. of 2008 I purchased a 14″ 44 W.C.F. ’92 carbine with the B.A.T.F. clearance paper work. Serial #979881.  I only recently realized that it has walnut, not gum wood, stock and forearm.  The wood matches nicely and the fit seems perfect.  The forearm measures almost exactly 7 7/8″.  Is this unusual or normal on the later Trappers?  Thanks, RDB
