Maroon variation - probably 1910 only. Hook couplers, white raised lettering, red trim with gold outline on roof.  Two headlights, two wire pantographs, bell and whistle. Note the one above has the correct light holder where you can see the threads.

1911 variation is black but o/w identical to maroon and 1910 variations. The example above has both wire pantographs missing. The example below with hook couplers appears to have replacement pantographs and headlight covers.

1912 - addition of automatic couplers and "A / D" switch. Two wire pantographs, two operating headlights.
