Well, I received a battered 16mm print (missing the first few minutes) of 'Shoulder Arms' today, and so I'm able to answer my own question of a couple of weeks ago.
Mr. Shepard was absolutely right. EVERY shot in this film is different - and superior - to the ones used in the Image laserdisc / DVD (which come from the 1940's 'restoration'

. What we're seeing there *is*, indeed, a 3 reel film reconstructed from alternate or second best takes. It's a completely bizarre - but fascinating - experience to compare the two. On the DVD you can see where, in each shot, Chaplin *almost* got things right - but in the real film he DID.
I believe someone mentioned that this original version of 'Shoulder Arms' was available on videotape somewhere - would anyone have a source for that?
And, of course, I'll ask again - if anyone has seen any of the other original First Nationals - were they ALSO modified to this extent? It's almost unthinkable to me that the rescue scene in 'The Kid,' for example, could be the 'second best' take, and I had a dupe of 'The Idle Class' at one time, but didn't notice any difference except one shot in the 16mm that wasn't in the other film - certainly nothing to the extent of 'Shoulder Arms.'
And I'll say again, it's an aesthetic CRIME to do this to Charlie's films, and even worse to pass this off as the real film. What's on the DVD is NOT 'Shoulder Arms' - it's a simulation of it constructed out of sub-standard material.
This abhorrent act is compounded by the Chaplin Estate's moronic declaration that they fully intend to stick to the 'replicant' films because 'that's the way Charlie wanted it.' Well, seeing as that he was cogent enough to realize that he could improve the 'second best' takes in the first place, I do not believe for a SECOND that he would have approved of his films being altered this way - no matter how much the visual quality of the film might be improved due to damage to the original.
David, I wish you'd return and weigh in on this.
