No there is only 1(maybe 2 if what I've heard is true) of those, there is smaller cars of different variations. But there is none like the CEBX 800.
And before this gets way out of hand. Read.. http://en.wikipedia.org/wiki/Schnabel_car
You're contradicting yourself. You're saying there's only one (maybe two) schnabel cars in existence and at the same time you're linking us to a wiki article which states that there are 87 in operation around the world... (more than I thought)
The CEBX 800 may be the biggest but that doesn't mean the schnabels build before it aren't still schnabels...
