I am not sure that Annapolis appears in the reproduction Mayflower sets. It certainly may appear in some of the originals, as American Flyer seemed to mix plates in later years, as they ran out of the differing plates.
American Flyer also used up the leftover name plates on small O gauge tenders.
The 19" baggage car is impressive, but is somewhat rare. I think it may be a Richart car, but do not recall. I have seen chrome versions of the baggage, as well as painted versions.
To my knowledge, the baggage car is the only add-on car. The only other way to add cars is to buy singles from people who have split sets up, or those who acquired extra's from MTH.
