Jody, several lens makers replaced the real Tessar's cemented doublet with a cemented triplet to get around Zeiss' patent. Ross, for example with the Xpres. But Xpres is really a trade name and later Xpres lenses were really tessar types.
Flor is an SOM Berthiot trade name, not a design type. I have in front of me some SOM Berthiot propaganda that shows cross sections. Flor includes tessar types, the cheating tessar type you described, 6/4 double Gauss types and 7/4 types derived from double Gauss.
