@woozelmom - Not to sound officious () or anything but, there can be several versions of the same movie prop made for different purposes like close-ups, distant shots, action shots, promos, etc.
So really, none of them are more correct than the other. I like to try to get as close as I can to the screen version but if that doesn't work getting close to any other version is fine too.
The other thing is, it's your prop, do as you will, it's just fun to make and have them!!
