Yes, the naming was astoundingly stupid.
The clamshell financials were:
- HP-18C Business Consultant
- HP 19B Business Consultant II
- HP 19BII Business Consultant II
The first part (HP-18C, HP 19B, or HP 19BII) is the actual model number. The rest is a marketing title. There may have been labelling variations regarding the title.
Whether the marketing title does or does not include "II" has nothing to do with whether it is a 19B or a 19BII. It either has the II
immediately after the 19B, or not.
If someone offers a "Business Consultant II" for sale, that's not enough information to determine which model it is.
