I've got a bit of information on the brand. My understanding is that Ranger was one of Schwinn's Chicago competitors during the 1890's/1900's. By the late '60's, however, it had just become the house brand bicycle for the Marshall-Fields department stores. This one is a '69 according to the date on the S-A hub (12-68), and I'm assuming was probably the top of the line for the store at the time. It's the only one I've ever seen of that brand. As pictured, this is immediately after I finished the restoration, later adding a Plestcher rack, front and rear generation, heavier grips and replaced the saddle with a Rampar copy of a Schwinn Suburban saddle - all for my wife who occasionally rides the bike. Unfortunately, the original saddle was on the parts rack the night of the fire.

Hope this helps. It's at least one iteration of the Ranger brand.
