Hobbymaster M4A3 Sherman. My only hesitation is that some of the detail is a bit heavy because the HM tanks are die-casts. The hull and turret shapes are quite good. If you are willing to do some finishing and fine detailing work, a lot of the 1/48 die-cast models are perfectly acceptable candidates to be brought over as true scale models. Several of the Classic Armor tanks are in this class, BUT they do need some work here and there, and unfortunately the tracks will need to be replaced on most of them, being rather poorly detailed cheap vinyl. I am going to do some of these for a Track48 article later this year. I have a couple of tricks to get the die-casts up to speed with minimal work.....
