Other Promo Ware
Here are advertising and promotional trays that are either not by Chance or a certain level of uncertainty exists.
Royal Observatory olive tray'Olive' tray measuring 8½x3¼-in. This width would appear to preclude Chance and Durographic (3½-in wide) so possibly Webb.
Barnham & Bailey trayA large tray (17.5x12.5cm) with square corners and flared at the top. Made for the Ringling and Barnum & Bailey 'Circus World' and copyrighted in 1973. Unknown maker, possibly US.
Dutch Sophia-Jacoba tray11.5x8.5cm tray made for a Dutch coal mine, which produced 'Eierbriketten' (egg bricks, or coke). Originally a German mine in Aachen, it was taken over (Dutch) in 1973 and this tray dates thereafter.
Carnaby Street trayQuite a few trays in this series exist. Produced for the Fulltrack company. Sized 6½x3¼-in indicates it was probably not by Chance or Durographic, but could have been Webb. The 01- STD code for London shows a production date prior to 1990.
Churchills Club, 1950sEvocative of the 1950s, as a London-based club, this tray might have been made by Webb Crystal Ltd.
