We have a Brass Water Tap Faucet Antique item.  It measures about 4 1/2" from the top of the tap turn to the lower threaded pipe x about 4 3/8" in W from the outer edge of the lower threaded pipe to the outer edge of the side threaded pipe.  The turn knob is about 2 1/8" across. At the deepest point it is about 1 1/4" in D.  The lower threaded pipe is just over 1" across the outside dimension.  The pipe on the side is about 7/8" across again outside dimension.  The tap will not stick to a magnet.  The brass is quite discolored from age as shown in my photo's.
