M113--Good job on the finish. It looks very good.
ShermanSam--If you are trying to make a fairly accurate M4A1 (76) from the Italeri kit here are a few things to consider:
1) The barrel is dead wrong (Rubio's is a fine replacement).
2) The antenna mount is British.
3) The tools are British and terrible.
4) The tracks stink.
5) The hatch for removing empty shells from the turret (on the left side of turret) should be raised up not sunk in as the kit is. A good illustration of what I mean here is this picture of Steve Zaloga's M4A1 (76):
Other than the few things above, as with any other kit there are small details here and there that could be added, but all in all the Italeri kit is darn good (especially when its age is considered).
