Congratulations on your Blob type bottle ( 1860-1910 )!!! You have a nice piece of New York City history. Complete with name and address and even date ,,,, Henry Muhler was what was referred to as a "Bottler". He used his bottles to be filled by other companies, sometimes beer, soda, and occasionally spring water. There was literally thousands of bottlers here in the city. Some years back I wrote a book called "Bottles of Old New York" I chose to concentrate on embossed style of bottles (just like your find). These included the manufacturer's name and usually his address, which in turn was an early form of advertisement. Most of manufacturer's buildings have long disappeared because of the expansion and growth of the city. In some instances, complete street names have been obliterated. Strangely, many early manufactures were not listed in the business directories of the period, thus making these bottles the only existing record available. This was the purpose of doing my book. I also show about 100 pictures of embossed style very similar to yours.
I hope, I shed some light on your bottle!!!!
Regards Simon....
