This is the only "VR" beer glass in my collection, a half pint one, which I've had for some time but only just noticed it has a Sowerby Peacock mark. It has the VR crown mark used between 1879-1901, the 323 office mark for Gateshead and GCC for Gateshead County Council, formerly a County Borough. I can't find an exact match for the shape and handle combination but it is similar to the No.1586 shown in the 1885 catalogue under "Cans and Seidels". I've also added a photo of an Edwardian pint glass also with a Gateshead stamp.
