You might be onto something.
I did some digging via Google, and that led me to page 10 of volume 72 of the United States Tobacco Journal.
For those who can't get the image, it states that the name was registered as a trademark on August 11, 1909.
I also found some language that seems to originate from an auction house about the Obak brand starting in the 1860s, but I couldn't find an original source. (The key is looking for the John Bollman Company.) My takeaway is that it's not impossible that the name was resurrected.
