This is what he said: (full convo)
Canvas came first, then Chassis, then Jensen Kimmit founded A-RT. Chassis was sort of like a transition before JK founded his company, and i don’t think it was ever released for sale.
He took the reference from a photo that was posted on JK’s instagram (but now it’s no where to be found… I can’t even find his account =_=#) So I can’t say for sure, it could just be something JK made for himself personally or it’s a prototype.
Best way to confirm this is with Jensen, but I have no idea how XD
