Not much light to shed, since this clock was purchased well before I was born! Yes, my grandfather grew up in Germantown/Philly (don't know what part, some areas have declined!). I know he worked for Remington and DuPont in Connecticut and Delaware in the mid-century years, so this clock may have been purchased by his parents in Philadelphia, or at some regional east coast store.
My guess is that he and his family probably shopped in the same store(s) as your predecessors, Greenacres, and had the same kind of taste. Those traveling clocks were quite the thing back in the day! I loved playing with it when I was a kid.
