Kevin,
I'm fairly sure that it is nitrate. Well, maybe not. I do know that my standard 8mm print of birth of a nation has vinegar syndrome and a slight warping to the film.
I have heard that "vinegar syndrome" can be caused by old magnetic tracks, OR, the glue for the tracks slowly breaking down.
I can varify that my "Birth", while vinegar smelling, is truly the sharpest print I have ever seen of this title. I saw a print of this on DVD, taken from "the best negatives available" (highly over-used phrase). I don't know as to whether they used 16 or 35MM, but my print on Standard 8mm is stunning. It has little surface wear as well, (on the original negative used).
The only sad thing is that it does have a magnetic soundtrack, but I have never been able to play it. A shame, as I have heard that it's supposed to be a commentary by someone who worked on the film, (that was stated by the person who sold me it.)
I don't know if this is on every print of this film, but it first has a "copyright" title saying that "every official D.W. Griffith film has this title" (paraphrased), and the second
title card is a statement against censorship. ("A Plea For The Art Of Motion Pictures"), before then finally getting to the main titles.
Another thing I found quite striking about the print was that it has perfect blacks, as well as the full spectrum of contrast, lovely grays. I have never seen such great blacks on any print, not even a Blackhawk.
I think it comes from at least the mid to late sixties. I mean, it at least has to have been from the magnetic sound age,
OR striped later and soundtrack added.
At any rate, as I said, lovely print! Just stinky.

Micheal,
I can verify,
and completely ...
Identify,
Blackhawk,
it is not,
but I fear,
vinegar
shot rot
and ...
the warping,
contorting
and perhaps,
distorting ...
images.

Osi,
I do not doubt your expertise.
If it is nitrate then I have leaned
something new.
Some Blackhawk titles that I own have a
"nitrate appearance", that probably have been taken from
"lavender"materials which give the results of a
print down with stunning quality.
Print down films are taken from the original
camera negative to manufacture a sparkling film print.
This makes your print a winner,and at least
the better and best of the companies similar to as Blackhawk Films that I had seen.
Although I have not seen all prints of this title because of it being a long feature when projected at silent speed.
It is worth trying to use either the Film renew or
Vitafilm products to arrest the "vinegar" before
it becomes worse. To achieve these results
some people prefer Vita film after soaking
a print for six months.
Vita film is expensive, but I know that
you should be able to get the curl out
of the film print when it is soaked in Film renew,
and then back wound against the curl or warp.
I have found that using steel reels that are not
warped and used on rewinds worked the best,
and without placing a strain on the projector.
There you can control the tension
on the film and lay it as flat as possible without
it becoming too tight on the reel.
I too have found that a mag stripe has
the potential to gas out to a vinegar scent,
because some of my home movies have this problem.
When looking at the side of the film reel,
if the print appears spoked then
the film is buckling and breaking down
in the vinegar process, and hopefully this is not the case in
your film print.
This is worth salvaging due to
the stunning sparkling quality, so that you may
be able to enjoy the film completely.

Isn't it great that we can all communicate about this great

Guys, there is NOTHING that will cure VS. The current VitaFilm product is NOT the original mix despite it's advertising. If it was, then it would be haz mat way above and beyond FilmRenew's rating because many, many years ago I used to use it and that shit was so strong I would get migraine headaches and would usually experience nose bleeds while using it, despite very good ventilation. Check the msds sheets.
On the good side it would appear that most of the cleaners on the market DO slow VS down. That goes for FilmGuard, Film Renew as well as at least in theory VitaFilm. I can attest to FG, as I've done my own testing as well as received countless happy emails in this regards. I've also read plenty of positive reports on FR online. VF is the only one that doesn't really have much backing other than the manufacturer. Regardless I've no doubt it helps. Leaving a film dry definitely appears to make vs worse.
Whatever you end up doing, odds are you are only helping a vs film. Do bear in mind you are NOT stopping or reversing the vs, just slowing it down and masking the odor.
