You could PM
@Benny as the chances are he will know, but I can guarantee there's no chance he'll see this thread otherwise
Like Taz said, your best and quickest bet is to use a vernier to know for sure
EDIT: Only just seen there's a picture... Which is of a 4th gen, not a 2nd gen. Don't know why it didn't show the first time I looked, but Benny has a 2nd gen which is why a suggested he might know
