Sorry if these are too obvious but I've tried searching the forum and have gotten quite confused so I thought I'd just ask outright: 1. Is the new modern chain replacing the old chain or is it just another option/choice? 2. Does the red flap (with old chain) come in silver hw? 3. I'd love a medium, red caviar classic flap with the "old" chain and silver hw. Impossible to find? BTW, although I'm in Canada, I have friends in the States and England who could help me shop. Thanks for your help. Confused in Canada.
