Don't ask me how but I found the maker is Hilger & Sons. It seems that it was a German manufacturer that had a distributor in New York City.
"Hilger & Sons was an importer of cutlery and hardware in NYC, founded 1848. Eventually -- probably in the 1890s -- it merged with Wiebusch, to become Wiebusch & Hilger, one of the top 19th and early 20th century US importers of German, Bohemian, and English cutlery (there were dozens of wholesale importers, most located in the cutlery district of lower Manhattan, on or near Duane Street". From a thread on Practical Machinist.com.
I verified that their mark is an H in a dotted oval with a flower (maybe a tulip). There's a lot of stuff on eBay and even Craigslist from this maker.
Thanks for the help. You guys didn't guess it but you pushed me to find out!
