Looks like my 3" anti-tank gun question has got everybody else beaten as well so I'll revive an old project.
Cavalier was effectively the bridge between the Crusader and Centaur. My big question is whose road-wheels and hubs did she carry. I'm nearly convinced they are Crusader (no holes in the hub and look slightly narrower compared to the drive sprocket) but would appreciate confirmation.
I am aware that the road-wheel spacing was changed on Centaur so did Cavalier match Crusader there as well?
