Hi ,
Almost certainly a late Victorian reproduction and intended as ale glass , the decoration being Hops and Barley stalks a common decoration on ale glasses of all sizes,the glass could be polished to look like new again by a professional glass restorer and probably cost around £20/£30 to do ,or you could have a go yourself using a dremel with polishing pad and cerium oxide.or you could try 'Autosol' which is a car metal polish and works very well .
Cheers ,
Peter.
