The M7 Howitzer Motor Carriage (M7 HMC) was an attempt to bring the support of the field artillery closer to the front lines and to make for faster deployment. The 105-mm howitzer was a common weapon and standard in the US army in WWII, the chassis was from the M4 Sherman. The kit contains 210 plastic parts and 46 photo etched metal parts, although many of them are unused. The track comes in hard plastic parts with many link & length. Part quality and accuracy are decent. The instructions look good but like other kits with many parts, pay close attention to placement of the small parts. The interior where the 105mm howitzer gun is placed looks very nice to me when finished, with a lot of 105mm rounds, tools and other stuffs. I was more than pleased with the finished kit, a very good addition to a WWII collection.
