Right on John...I think there were only 234 of the L-34 68 Novas and only 48 of these TH400 models. They actually made more L78 cars (667). I consider these 68 L-34 Th400 cars a kind of a "Jr. COPO" because so few were made. They are very rare and seldom seen in the hobby. Hopefully more may come out of hiding or be found..
