I love this post!
I have two of the vases pictured, together with other Etling pieces, however this also kind of answers my own post about Carrillo. It does seem that Etling, together with his own glass-workers and his entire family met their deaths during WWII in concentration camps, and his Salon in Paris, was also a casualty of Kristallnacht. Sevres, retain several Etling moulds, although I doubt that they have them all, and also have reintroduced several Etling patterns over the years, but none of these have been attributed to Etling and are signed Sevres. Whether or not this out of courtesy one couldn't say, but it does perhaps bring the designs by Carrillo into the equation...
Oh, and BYW, I'm up for purchasing a copy of the catalogue too, if you can obtain a copy! Pleeeeze.
There are currently a pair of the Swan Bookends in opalescent for sale on eBay, and the sailing ship is also interesting to me, as I have a very similar example as a lamp in deep smoky-grey signed by d'avesn, who also used the facilities at Choicy-le-Roi as well as Sevres.
