One of the points Andy was trying to make was that not all glass from the same manufacturer is marked, even within a range.
Your bowl is almost certainly 1930s German because the pattern is exactly the same as on the marked German vase he shows.
But I did read the caption incorrectly yesterday because he actually says, similarity of colour and design, i.e., pink with chevrons, are insufficient to attribute to the same manufacturer and country when comparing the vase with your design on it and an Athene bowl :oops: :oops:
