Notes

Also called CATALAC 30.
The first and most popular of all the Catalac models with more than 250 built. A shortened version became the CATALAC 8M which sold nearly as well.
In 1994, a new version was introduced from a different builder using the the original 9M molds. This was the CATALAC 900. (about 20 built)
