If you were going to build just a couple of the HB or Bandai Shermans, reworking the parts would not be a chore. But, I'm looking at probably two dozen kit corrections. The HB M4A1 takes about 1-2 hours to do, especially if you use epoxy putty, which sets up fairly fast. The problam with the HB M4A1 is the upper edge of the hull is too narrow, so the sides taper in toward the top too much - it gives the tank a turtle shell appearance. BUT, HB got the rear correct: angled rear plate and no cutout, a straight tailplate. It's maddening..... The whole Sherman series is like that, basic shape errors in EVERY Sherman kit, and then small esoteric details that are correct, even stuff that Dragon hasn't gotten right yet.
