Unfortunatley I'm nowhere near as skilled as some of the cats around here doing custom builds. i would consider an older version of the M4 but I'm not sure which one has the more traditional style turret and the really neat "bolted section" tranny cover? And is there a conversion kit for that style? I have no idea what Mato was thinking when they decided on the jumbo...definately one of the ugliest Shermans produced...especially with the oversized airsoft barrel....iiiich
