Dan S. W. thanks for the weight info. I just measured the barrels on the E. Smith. The chopper lump barrels are 27 1/2" long. An unusual length. Chokes are .018 and .028 with still the original .729 " max bore diameter. Minimum wall thickness is .028". Stock lop is 14 5/8" over checkered butt, so the only visible item possible related to the light weight is the barrel length.
