Bill,
Now that you mention it, I think the ones on the floor are the newest. I guess that's the way it works for me, too! As far as the cases are concerned, I've got a shelf in the furnace room for them. Out of sight...out of mind. Otherwise, there'd be no way.
By the way, I'm still incredbly jealous of your Series I. Makes me want to kick myself for not bidding harder on the VERY few minty fresh ones that came along on ebay.
Regards,
Jonathan
