I know one is for PW ZW's and the other for modern ZW's, but how can you tell the difference between them without the packaging?
Reason I ask is because I just bought one off of EBay, and the seller doesn't know which one it is.
I asked him to look for the number, but he says it isn't on the item.
I googled pics for each, but they look exactly the same.
Here is the link to the item I bought..... you may have to scroll down
