Is that an Electrolux sprayer? If so, I didn't know that they'd brought the item back. As far as I can tell, the last sprayers were available with the Golden Jubilee/1205-J:
Yes that is an aerus/ Electrolux sprayer. It was included with the guardian until that model was dropped and the legacy model. They stopped including it with the legacy model a few years ago.
I have one of the old glass ones which works much better than that blue plastic one ..
