The references to the extra hole being drilled in Berliner discs in 1899 have appeared as recently as Dec. 2011 (p. 23: "Seaman...drilling...), haven't they? Have I misunderstood that footnoted description? I was merely asking (rhetorically?) how the extra (tiny) hole could be drilled in 1899 when there were no (real) Zonophones on the market yet. 
It appears the subject has shifted...  Again.  Now to Zonophone 
records in this thread? 
 
 
I have no hard evidence as to whether Berliner records were being drilled in late 1899 or only in early 1900.  However, since a large supply of records would need to be available 
prior to the introduction of the Zonophone, and since the existence of a Zonophone record laboratory/factory wasn't announced until February 1900 (
Phonoscope November 1899 issue - published in February 1900 - p.10), it seems likely that this activity began in 1899.  There certainly was much activity cited in 
The Phonoscope and in other sources as having occurred in 1899.  (By the way, neither the sentence to which you refer cites 1899, nor does footnote #3 (the typo in which has already been explained weeks ago in the "Earliest Zonophone?" thread) mention the year 1899.  I still think it a likely year.)

We also have this statement: "It is not known when Zonophone records were placed on sale, but 1899 seems a likely year." True, this claim was published in 1983 (APM, p. 3), but has presumably been modified over the years.  

 
As noted above, Universal established its record production facility by February 1900.  In 1983 I didn't yet have access to 
The Phonoscope, so yes - I have long since modified that date.  Is there a point to this?

Absolutely.  Data is golden.  The rushed interpretation of that data can sometimes tempt us to make claims that later turn out to be false.  A conservative route is the best policy; one which I have attempted to pursue in my writing.
I have offered no public critique of any forum member's past published work in this thread.  I don't consider it good form.  However, if this line of "questioning" must (really?) be pursued, I suggest that it be done via PM or email.  In this way others may be spared reading it, and I will feel more free to respond without the wise and accepted restraints of this forum.
