Hi Ron,

Welcome to the forums!  There isn't much to differentiate the two, you're right.  In fact, the only way to know for certain is going to be a picture of the inside, which you're welcome to have the seller e-mail me directly with it if you want.  zen@decware.com

Otherwise, you could have the seller ship it here and we could install the CCE mod if it's not already there.  If the seller is the original owner, we may be able to just look him up in our database and see what he had.

Thanks,

Steve
