Hi Max the one i had is in the British glass between the wars book page 67 -1929 lighting glass under the name Vesta glass,Egyptian Stork. When i acquired it i gave Eric Reynolds a call he was so excited it was the one panel he needed to complete a set,he took the overnight train from Devon i met him in London it had been raining he sat on a wet bench and was trembling while unwrapping it he wouldnt trust me to unwrap it he kept saying are you sure its the right one,it was. Off went Eric back to Devon a very happy man ,one of the nicest people you could wish to meet. In Erics book page 23 he shows a panel the twelve labours of Hercules. Eric if you read this i hope you dont mind me telling our story, Regards and best wishes John.
