What brands of elevating scrapers used a Hancock design bowl?

I've been told the Terex S17E. That bowl sure looks similar to the Wabco. Maybe I'm wrong. But the stationary cutting edge, and the strike-off blade attached to the moving floor have similar designs. The large pipe across the top rear of the bowl, etc. Later designs have the laid up box fabrication of the bowl walls like the backside of the Cat six way blades.
Tying the lower front of the bowl walls together with a cutting edge would sure strengthen the walls at the lower front
