As I'm sure you can imagine, more and closer photos would help with identification. However I would say, if the truss rods on the front fork are original to the bike, than the bike is most likely from the late teens or later maybe even as late as into the 1930's judging from curves of the frame design. It's just too hard to say with any certainty based on this one small photo, but at the moment from what I can see I'm thinking somewhere between 1915-1935 era rather than 1890's or early 1900's. Maybe once I see better photos I might be influenced otherwise especially if the front fork truss rods are not original to the bike because those were pretty much 1910's and later.
