In days of yore, a plumber with some age on him could take one look at any faucet and tell you what it is. Those days went away about the same time as 8 track tapes.
We need pictures of what is underneath, and what is inside the valve body. If this is mainstream, it has styling which could be Kohler. But there are so many generic knock off faucets from China, it has become very difficult to pin it down. Anyway, for starters, more pics.
