AFIAK, only the 1's used the foam around the prism. I have never had occassion to take the top cover off of my 2n as it has never had a problem and the prism shows no degradation. John Hermanson at Camtech could provide specifics as to model/SN cutoffs. He used to post comments here. Let's hope he's just busy keeping all those wonderful Oly's running!
