I don't own any Grognards models yet, or any WGA models for that matter, as I've been unemployed for most of the pandemic. But I hope to be employed soon. in the meantime, I've worked on some 3d model kitbashes for my future Grognard army:
This is a Leman Russ proxy based on a French ARL-44 tank, which was briefly in service immediately after WW2. its shown here with the Vanquisher cannon, as its the most faithful to the original ARL 44 gun, but the turret is modular and thus the gun can be magnetised.
This is a Chimara Proxy based on a WW2 french Char B1 Bis. I call it the Char-mera. the Chimera is actually fairly similar. I mirrored the body(CharB's have the hull gun on the right) and replaced the standard CharB turret with a Chimera turret. I also added a rear hatch.
This is my FT-pattern Sentinel. the body is an unmodified FT-17 without the tracks. my friend used this as one of his test models on the new resin 3D printer he got this past summer.
