Dirk what size is your bowl please?
I'm really not trying to 'make' these WMF, just trying to pull possible links together at the moment:
-On page 78 of the WMF book there is a vase at the top right (totally different to these) but has an amber shading to green colourway effect.
- the foot on my lamp is visible on many pieces in the book.
- on page 101 there are two x three footed bowls with applied feet like Dirk's bowl but the shape and decor of the bowls is different,however the feet look about the same size and shape as Dirk's bowl and they are clear I think whilst the bowls have a decor.
- and on page 101 at the top row show it shows two vases as per the one on the GMB link I gave just above here and both have three little feet.
