I have not managed to find any info on this makers mark. Found lots of old questions like mine on message boards, but never an answer. If anyone has info on this mark that would be great! The tray is 14.25" W x 1.75" H & has 3 ball feet.
It's a silverplate mark, but I forget whose. The tray is classic 50s/60s barware. The formica surface was made to be alcohol-proof and still look good. These sell like hotcakes to anyone wanting retro barware.
A bunch of companies made the plated surround, IIRC. There may have been some in sterling and natural wood, but I've never seen any.
