This is a good point. Much depends upon how reliable you know the source to
have been concerning buying only one or another kind of tape, being
meticulous about keeping that brand in its box or on its manufacturer-identified reel
(which some people are/were not), and so on. And in some cases, such as
archives, one may know little or nothing about the source's habits. In my case, the
tape collections I obtained came from people I knew and I could be sure that if
a tape box or any other identification named a certain manufacturer, it was
accurate about the tape itself.

I've been reading this thread with a bit of an interest in the topic, but
since I've only ever run across a few reels of acetate based tape, it's
more cursory interest than anything else.
One thing I've noticed, though, is that many times, the name on the box, or
the name on the reel are NOT reliable and the tape on the reel inside may
be something altogether different. So, would knowing the information that
such an information base would contain be of any use? If I have an Irish
box with a reel inside that says Ampex, how will the information base help
me if the tape on the reel is Scotch?
How are people determining what type of tape is actually on those reels?
