We have California Faucets fixtures in one of our bathrooms, and we quite like them. They seem much more substantial than many of the others. I suggested them because the shape of the faucet in your picture looks very similar to our bathroom faucet's shape. Good luck!

have no idea on manuf. , but I'll bet dollars to donuts that if you pry out the blue and red dots with a knife or a dental pick you'll find the screws that hold the knobs onto the cartridge stem.
