... this bowl has the first flower holder I remember seeing that has two layers of brasswork so that stems are held at two points - this was designed for precision arrangements. ...
John — If you look in Reynolds, pp16–17, you will see your Walsh flower holder design illustrated on an example of Vesta Venetian
dating from November 1907. On the opposite page you will see an illustration clearly showing the two layers of brasswork on a Walsh flower holder with a different rim, this time on registered design 582840 of April 1911 (also illustrated in Gulliver). I will have an example of this design on my stand at Cambridge next week, and, like yours, the metalwork is past its best, but it's all original and it has not been "improved" or "restored" in any way. It also has a beautifully engraved registration number on the base.
Sticklers — should that have been "Gulliver.)" and "has passed"? I'm getting sloppy and I suspect my Eats, Shoots & Leaves has been tidied up, as it's not where I expected it to be.
