These are Regular 8mm on 200' size reels. All have leaders on them and appear to be in good condition.
Boxes have seen better days and some have library labels attached but are not falling apart. I am familiar with film stock and these films are not in bad shape. I just don't have time to project them. I examined the first few feet of each and only found one with damage. (1" of damaged perfs near leader on "Doughboys"). Otherwise, I did not find any damage at all and could not detect any evidence of splices other than the leader splice. There may be a splice somewhere in all this, but it was not visible to my eye. Film of this type rarely survives without some scratches on the emulsion... I assume this would hold true for these films too.
