What should have been the simplest of answers to dig up ..... ya right.
What you want to build is right on the cusp of many, many changes in the Sherman. For the time frame that you want, I can't find a single N.A. M4 picture in any of my references. Lots of M4A1's, but no M4's. The text references the M4, but also states that they were probably M4A1's.
Does this mean there were no M4's used by the U.S. at this time and in this place, absolutely not. Never, never, never say never when talking about the Sherman.
Now this is what I do have:
- both the M4 and M4A1 served with the British forces in N.A.
- some American / British Shermans had Direct Vision slots ..... some didn't.
- some of them had the early mantlets and some had the later style mantlets
- some had the M3 suspension and some already were fitted with the M4 suspension
So where does this all leave the Tamiya Sherman kit that you have you ask.
If the U.S. did indeed have the M4 in N.A. (which I strongly suspect they did and I'm just not seeing the pic in front of my face), the only thingthat you definitely have to change is the suspension. Even though the kit comes with the M4 suspension, it is the later type with unswept return roller arms instead of the level ones. These are the type that come in Academy's M12 kit and DML's OOP M4A1. I'd still get the TW M3 suspension set and use it because it is just so rarely seen on a Sherman kit. Everything is in the Tamiya kit will be just fine for your build. If you have a photo to work off of even better (and please forward it to me so I have one too).
Most of all, stop dying, start building and have fun with this build.
Happy Modelling and God Bless
