Size is 3 inches tall and 2 inches wide. Melon rib design, Top has some dents in it and some brass showing through finish, Couple small dark spots on the back, may have been made that way. Design is in good condition. I have managed to collect some of what I call Victorian glass kitchenware over the years. I really do not know enough about any of it to tell you who exactly produced it. The major players in the field are in my title. Condition on these items vary but there is often quite a bit of wear on some of these tops may have dents or corrosion from salt. Please look at the pictures carefully.
