as soon as I saw the vase ian put on ebay the first thing that came to mind is Perthshire aswell, colourways mean nothing as I have several pieces of Perthshire that the colours look same as monart, im still sure that your bowl and the vase ian sold are Perthshire and not monart
I have just purchased an other Monart DF shape bowl/charger in the same colourway, but with a post war label.
The colours in this image are a truer representation of the colours compared to the previous image ,earlier in the post.
