I thought many of the followers to this site might find this interesting. After publishing my book last December and distributing the 125 copies to the purchasers, I took a break from my exhaustive researching, however the last three months has been pretty productive in trying to narrow down more precise dating for some bottles that have a wide range of opinions as to when they were embossed. Here's a list of what I've been able to prove through written evidence.
A. Barbier Aromatic Schnapps - August 1857
Rowler's Rheumatism Medicine - August 1861
Fish's Infallible Hair Restorative(rectangular bottle)- April 1863
Fish's Infallible Hair Restorative(round bottle) - November 1864
J. F. Cutter Extra Old Bourbon - February 1871
Addendum
I read the comment by Dale Mlasko and will try to answer his inquiry here as an addendum to this post since his comment has been erased. The Fish's bottles story involves 4 major players, I have been working on the complete story on this product for awhile now and hopefully will post it shortly. It will make it much clearer as to why the bottles came when they did.
As far as the Rowler's bottle, some collectors attribute it to the first or second glassworks as their product. My recent information does not lead me to that conclusion anymore.
The Adolphus bottle I believe is a product of the first S.F.G.W., although I do not have real strong evidence to back this opinion up. Hopefully in the future a more concrete conclusion can be had.
Recently I have been very intrigued with the Turner's square bottles, and have very recently come across interesting information concerning these bottles. Ever since the Auburn show two years ago when a few collectors brought examples of these to compare, I have wondered whether all 7 mold variants were made in the East and whether any of those molds were brought West for use. I am finding the information on this very interesting.
