Not for 1949 and later. The striped quadrant is a 1940s era shifter, later than the flat faced quadrant and the black print quadrant. But the New Worlds, Continentals, and Superiors I have owned that had quadrant shifters all dated to no later than early 1948. The 1949 and later models I've owned all had handlebar click shifters. The 1949-50 had the short-lived Silver face shifters with black writing, followed by the common window shifter. After 1950, also the common window shifters. Some shifters include the "idiot proofing" solution of the Bottom gear lock out rivet. A number of shifters produced by Sturmey Archer in the 1950s for the US market (particularly Schwinn and Columbia) of the window variety have lock-out installed below the "Low" gear and above the "Bottom" gear because not all shops in the US knew to set up the three speeds on gears 2,3,4 (not started on gear 1 or bottom).
Not a huge deal if the parts were changed, especially fairly early in the bike's life. Usually these kinds of bikes were well-ridden because that's the kind of owner you get with a sporting machine. Good paint on this one too.
