The newer version with the notches was introduced shortly after Dark Gray was
replaced with Dark Bluish Gray, so it's possible that some sets contained
the new part in the older color.
The set was released in 2003, so it should have included this part in dark gray
instead of dark bluish gray. However, all the other parts in the set are bluish
grays, so the year of release for this set may be incorrect since the changeover
occurred in 2004.
