I had a friend stop in this afternoon and we got to speculating about the sink hole. Is it possible that the old faucet used to stick out of there? If it had hot water and cold water knobs up above it, with the faucet down below. I just can't figure out how they have rigged up the single lever faucet that currently sits up above the hole. Maybe the hose part is angled. It is also possible that it held a brass soap dish, but when I looked into the hole it seems like it extends down a ways as if to connect to a pipe/tube.
Thanks for your help in try ing to figure this out.
