Frank, do you know the address in Molesey where this glassmaker was based? Molesey is very close to where I was brought up and to where my parents live now (literally just over the Thames). Paul and I visit the charity shops in East and West Molesey fairly regularly (East is the posh bit near Hampton Court, West is the not so posh bit near Walton on Thames) and would be happy to see if there's anything still there.
