Arne jacobsen toast rack

I think this is an Arne Jacobsen toast rack from the Cylinda-Line made by Stelton. My question is does all Stelton pieces have there name on it? The bottom is marked Denmark stainless steel 18/8. I have seen some with a sticker on the bottom and others with Stelton etched on the bottom. The design seems to be exactly the same. If anyone can shed some light on this, I would greatly appreciate it!
