So… I have this from my Folk Horror project (although do not appear to have taken photos since it was finished), how would you stat it for Dragon Rampant?

I’ve been inclined to treat it as a greater war beast for the armour, adding ranged attacks. But don’t think the move should be as high as 10. Really I see it as moving slower than a man. I’ve also considered heavy ranged, but then that doesn’t have the armour.
I see it being very heavy, slow, well armoured but with no melee. Thoughts?
Has anyone done Empire Steam Tanks in DR?
