Asher Taylor's Sacramento connection

Several years ago, while searching the trademark files, I came across Asher S. Taylor's claim for his bitters. There it was, clear as mud. Were, in fact, the AT& Co bottles filled in Sac'to? If you use his trademark application, and the accompanying documents, it would certainly seem so. If that is the case why have none of these bottles showed up in local digs? Very few have been dug, with the exception of the dozen, or so, nice ones from the "Dig of '98". These examples came from SF, not from Sac City. Do you have the answer, Warren? I was disinterested to pursue it forward, but you may have.
