Mike, sorry to have taken a while to get back to this. And thanks for confirming the source of the illustration as being in a leaflet from the Pressed Glass Collectors Club, which does mean it will be removed from the Board.
I am also informed that the same illustration is in Jenny Thompson's book too, but that is also subject to copyright. And other folks' searches of the internet have not found an equivalent image.
Paul, it would be very useful indeed if you can "grab the details" for the B & T Rd numbers.
