I just had a look at an online
review of the kit, and it looks like you still get the late one-piece tranny and wide gun shield needed for a Canadian tank in NWE. However, it comes with the very early bogies seen under M3 Lees, so you'd need to swap these out for the later parts as included in other kits. Fortunately there are a few of us folk who have spares to offer...
The other big gap is decals - you'll need to identify your chosen unit and seek some AM markings. Again, asking the community here is a good way to go, especially as you only need enough for one tank.
A little while ago I built the Tasca "cast hoods" kit as a Canadian tank in the Netherlands, and backdated it to the earlier DV configuration with a spare hull ordered from Tasca. I did a build log here on Armorama that got turned into a
feature and you might want to look at it for detail ideas.
Let us know how you get on!
