"Britain's Biggest Barfitters!" Probably no empty claim either, their vans were all over the country. I got to drive one occasionally in the 50's, a Morris 8, delivering orders to pubs around the North West during school/college holidays. Royston Chambers was at the helm in those days and his two sons John and Martin were somewhere in the equation as well as other family members.
Both my great grandfather and grandfather were pewterers, first in London then Birmingham, the latter, if not both, with James Yates. My dad, Clem, joined G&C as an office boy in 1910 and, WW1 service apart, remained until his retirement in 1960, managing the Manchester branch for many years and ending up on the board of directors. Somewhere amongst old family papers I'm sure there's a letter or two from old Sir Cornelius to Dad - very formal.
My son has charge of the few remaining pewter pieces of my childhood home - a matching set of four (I think), gill to quart, plus a more plain, one-off pint tankard which is inscribed "Made by my father" on the base. One downside - we never had two matching glasses in the house, just a cupboard full of odd samples.
