Faucet for bonus well water line?

House built in 1967. Currently trying to replace the kitchen faucet. Original setup had 2 cold water lines and 1 hot water. One of cold water lines was softened and filtered water. The other line runs well water. The well water is nice for plants, but that's about it.

Where do I go to buy a basic spigot to add onto the sink? Like the real basic ones from a 1920s house where the Hot and Cold water came from separate faucets in 1 bathroom sink? What's this style called? Any suggestions?

I would like to keep the well water line for the plants.
