The earliest of the clockwork trolleys. The 800 used the body from a princess car with a clockwork mechanism inserted for power. The one one pictured above is one of the first as it has a full lithographed base with cross hatching. It also has the two color roof with handpainted ventilators. 

This variation has a one color roof, but still has the hand painted vents. Note the fully cross hatched frame, used on a car not cataloged until 1909.

This variation is somewhat later in that it has a plain frame and a plain single colored roof. 

Note the front bumpers found on these trolleys - the one on the left is earlier than the one on the right.

This is what the whole set looked like when set up.
