Mystery Perfume....how do I research?

[webe142]

I dug this little beauty today. It came out of an 1870s trash pit. I'm assuming it a perfume. Is there any way to tie it to a specific brand or manufacturer? Can anyone identify? Or better yet, how does one research a bottle like this?

I'm envious-a beauty! Just to close the loop on this, a pontiled example of the bottle is listed in "American Bottles & Flasks and Their Ancestry" by Helen McKearin and Kenneth Wilson. I don't know of any other good sources for these American colognes.
