Fantastic line-up of turrets. How are you going to sell these - by including them all in every kit?
Of course NOT the case! Depending on which variants, some Sherman kits will have the
T23 turret and some will have the 75mm version. However, all kits are cross-platform
compatible, meaning that you can swap turrets and configurations with each other.
That's also true for road wheels & tracks and transmission housing too!
This is why this M4 Sherman project took so long to complete! The "skeleton" structure
and key component parts had to be specially designed to be compatible with various hulls
and parts that are not yet designed.
Hopefully, we should see three kits being able to get released before Q1/17, namely,
M4 / M4A2 / M4A3 plus some of their variants too! As for M4A1, it had to be sometime
next year; and M4A4 will be much later!
