I have both the Skybow and AFV Club M41s. Both are entirely different kits. Personally, the Skybow kit looks better in the box, but both are great kits, far superior to the ancient Tamiya kit (it wasn’t bad for its day).
The AFV Club kit is what put Skybow under. Skybow put all their money into a highly requested kit and AFV Club released theirs first. Skybow’s kit is rather rare now, not many hit the market.
AFV Club ended up with many of Skybow’s molds. I do not know if the M41 was among the molds they received. I doubt they’d buy it since their’s is just as good.
