Hi,
The posy bowl and the barrel shaped vase both appear to be from the 'Rainbow Ware' range produced by Stevens and Williams in the 30's and 50's.
I have handled an identical spherical, deeply ribbed, vase in green and gold (amber) and came to the conclusion that this is from a different factory. From memory I believe the finish on the base is wrong. The deep ribs are uncharacteristic of S & W and the colours do match their palete. There are too many question marks concerning this vase therefore I do NOT believe that it is by S & W/ RB.
