Looks nice. It's an M4A3 medium tank with Ford engine and 75mm gun. I actual use, later versions of the M4A3 (with later hull) became the preferred ty[e for the US Army in Europe from the fall of 1944 onwards and in the Pacific from 1945 onwards. The later versions came with 75mm or 76mm guns or 105mm howitzers. Oddly, early versions of the M4A3 like this were held in the CONUS as training tanks until they were repaired and sent overseas in 1945.
