eco-Drake CEFIONTECT CST744EG Question

This is probably a question covered before -- but I couldn't find an answer after a quick look.

I purchased three eco-Drake CEFIONTECT toilets, model #CST744EG and recieved two pieces for each:

TOTC744EG-01
and
TOTST743E-01

The bowl is CEFIONTECT, but it looks like the tank is not. This makes sense, as the bowl is what is going to get dirty.

I just wanted to check - is this the standard way that TOTO sells the drake CEFIONTECT toilets?

Much Thanks!!

C744EG-01
and
ST743E-01

These make up the CST744EG-01

CEFIONTECT is only in the bowl.

Though they do make some lavs with CEFIONTECT too.

Thanks Terry -- Appreciate the quick response!!
