im probably completly well off and its just a "similar" type of thing but whilst at an antiques fair today i saw a metal tray with similar glass rods with metal ends as a fitted trim all the way around the tray, i believe it was made like that as the metal was fixed to the tray and firmly gripped the rods, looked very pretty and quite similar to these rods, i did ask the chap about it but he didnt know anything had bought it in a lot at auction.
