Here's the M4A3 as it stands now. Most major assembly has been completed, and all that needs to be done is mount the stowage rack and spare track links on the rear hull, as well as the tank commander's hatches. One negative point about this kit is that the loader's hatch is molded close, and requires surgery in order to model it open. So I understand, newer issues of this kit modified the mold so the loader's hatch can be posed open.
Paint jobs on these tanks were pretty standard Olive Drab, like most US Army equipment during WWII. While plain OD is often used as a point in the detriment for modeling US Army equipment in WWII, it can actually weather in interesting ways, something I'd like to really bring out on this kit.
Another modeling point I'd like to explore is stowage. Many period pictures of these vehicles in service showed vehicles loaded down with lots of crew stowage. These vehicles were designed for extended operations in the field, so the crew tended to acquire a lot of equipment to make their home on wheels more livable. Much of the stowage for this vehicle will probably come from the after-market, though I have yet to decide on what exactly that will be.
