American National Standards Institute (ANSI) & American Society of Mechanical Engineers (ASME) produce industry standards for plumbing fixtures as well as other building products. That number you posted was one of their numbers, not the model number of your faucet.
I'll recheck. these numbers are at the base of the faucet, on the back of it.
It says Kohler
that's what it looks like to me. would numbers be anywhere else? thx.
