Werrbach, L. - Milwaukee (W. Hill scatched on bottom)
This is the "large lettering" variety and is stamped "L. WERRBACH" - not a rare variety, but this example is interesting because it appears to have a name crudely scratched on the bottom under glaze - "W Hill" - perhaps the name of the man who made it? Presumably the bottle was made at the Charles Hermann factory. Some research may tell us is a Mr. Hill worked there in the 70's or 80's.
