Actually if you look at the pictures of the real barrel, the plastic one pretty much nails it. A metal one would be overly complex, and probably not add much to the look. On the other hand the tank really needs new tracks, the rubbery plastic used doesn't fit at all which is a shame. I had to scratch build the PE tow cable holders on the back because one of them flew off into the unknown, so more PE on the fret would have been good. But it does build into an interesting little tank, but it still looks undersized when placed next to a Sherman, especially the small top hatch that does not fit any comander figure I tried.
