Could be a Homo Faber. Chicago IL c1900. Whether it was made by him or for him is uncertain.
Most Chicago made banjos I have seen have twenty brackets, this one has twenty-four. The peghead shape resembles both Lyon & Healy and Slingerland but is not exactly like either one. My educated guess would be Oscar Schmidt or Stella but the 24 brackets are not normal for them either.
Whether the HF mark was from the factory or added later is uncertain. The banjo was likely made as an open back. The copper, or brass, resonator probably was an add on feature. Add on resonators were a common accessory that were available for open back banjos after resonator banjos became popular from the 1920's on.
The best way to find out any further information from the banjo itself is to use a socket(5/16" or something close) and unscrew the resonator bolt. Take the resonator off and see if there are any markings inside the rim or on the dowel stick.
BTW homo faber is Latin for "man the maker" or "working man". Are you pulling a funny there, Wayne?
This is going to be an Oscar Schmidt - pretty sure.
When photo made of interior of banjo please give us a good shot of the devise that stabilizes the neck.
No, not at all. The name is listed in a document on American Fretted Instrument Makers.
