Here is “Palace” car 07 at Camp Street, inbound on Canal.  The presence of large numbers of parked automobiles suggests a date no earlier than the late 'teens.  The “Palace” cars were renumbered into the 600-700 series around 1918, so the picture can be dated to approximately 1917.  The car sports X-gates at its doorways; these cars were later rebuilt with sliding doors, and still later, some got folding doors.
